Simple Instructions To Build A Windmill For Everyday Use

With oil prices moving higher and higher, power costs tend to follow the same trend. Given that our daily life relies very much on the consumption of electricity, getting your power from alternative sources is an attractive option.

The sun, water, and even wind are viable sources of energy. What’s more, they are renewable sources of energy as they are continuously present in our environment. More and more people now want to set-up their own windmill at their homes. With the many instructions to build a windmill available out there, it is up to you to find the one that is easy to understand.

Here are some helpful instructions to build a windmill:

Basically, there are several distinct types of windmills, based on the direction their blades spin:

1. The Horizontal upwind, where the wind hits the blade before the tower and the shaft stands horizontally;

2. The Horizontal downwind where the wind hits the tower prior to the blade; and

3. The Vertical Axis, mounted on short towers and its blades are pointing upwards.

Essentially, a windmill has four componants that must be given extra attention:

- base
- tower
- blades
- nacelle

In constructing this structure, the main objective is to maximize the conversion of the wind’s energy into electricity. Therefore, it should be tall enough to take advantage of the wind’s action in obstructed terrains – an average tower usually stands at 5 feet.

The base must be strong and heavy compared with other parts, to assure a sturdy structure because it is the principal foundation. It is advisable to use materials like sandbags or concrete, and in the case of a five-foot windmill, the base must be at least 18 inches square thick and 20 pounds heavy.

The tower supports the blade in capturing wind energy. There are many approaches when constructing it. You can either use guyed lattice or steel and pipe tubings or make them using a jin pole or crane.

The nacelle attaches the blade to the tower and contains copper wires and magnets that run the blade and help convert the wind’s energy to electricity.

The blade is the propeller used to capture the wind’s energy, so it is necessary that the blades are able to gather the flow of the wind easily, turning with the least potential resistance.

Materials to be used for these parts must be lightweight, so you can make them from plastic or PVC pipes. Note that in strong winds and storms, the blades can pose a danger if separated from the structure, so be sure to lock in the blades tightly, keeping safety precautions in mind.

Considering that a simple windmill could cost at least $40,000, constructing one for personal use can be quite expensive, but utilizing what is around you can help you save some expenses.

It is thus recommended to recycle parts in order to cut your expenses. Following these simple instructions to build a windmill will enable you to create one from scratch.

Windmills are just the beginning. To learn more about solar and wind power, go to Solar and Wind Power For Residential Homes or if you are looking for a simple way of building your own residential wind generator, see our Energy4Green Review.

Water – The Worlds Most Precious Resource

Water is one of nature’s most precious gifts and a resource we depend on for our life. Water is essential for everyone. Water is fundamental to all life forms, affecting all ecosystems and the various uses to which it is put. Demand continues to rise rapidly as the worlds population grows – water use per capita also increases. This is fast becoming a serious problem because the supply of water is finite. Only 3% of the worlds water is fresh. Refer to Enviromental technology for more information.

According to the World Health Organization, “safe drinking water is fast becoming the world’s most critical resource and a global concern as more than a billion people worldwide lack access to it”.

Here are a couple of good reasons for their concern:-

=> Unclean water is the second biggest killer of children, claiming more than two million lives annually.
=> drinking water is listed as the Number 4 health hazard in the US. Safe Drinking Water is constantly in the News – politicians would like it to appear safer than it is.

Water is indispensable for human health and well-being. A regular, adequate supply of clean drinking water is one of our essential basic human needs and often a factor in survival. Not only is clean water essential for everyday life, it is essential to economic growth and poverty reduction.

Unfortunately, Water is something we ALL take for granted.

Clean drinking water is one of the world’s most precious resources. Under US Federal law, bottled water is classified as a food product. As is the case in most western countries. Go to enviromental products for more information.

As a result of the way water has been marketed over the years, many consumers believe that, bottled water is safer and healthier than tap water. Why wouldn’t they think that when they have been shown graphic images of how the condition of the once-clean pure water is transformed by the time it travels through the delapitated pipes to our homes.

It is no wonder that in this day and age bottled water is becoming more and more popular. Sure bottled water is convenient, but it is only as safe as its source.

That same marketing has pushed the price of water – “sometimes dramatically” throughout the world to the point where it is more expensive per litre than petrol.

How much water is enough?
The “recommended” daily consumption of water is somewhere around 60-80 ounces, however alternative health care professionals will tell you should be consuming 50% of your total body weight in pounds in ounces. Regardless of the virtual water that you get from your diet. Virtual water is the amount of water that is embedded in food or other products needed for its production.

Water is the safest thing for you to drink. In many ways, water is a miracle liquid. Water is essential to good health, yet needs vary by individual. Although it contains no nutrients, water is a vital component of our diets.

My 2 cents worth
Make no mistake water is the most important liquid in the world and having a supply of safe drinking water is everybody’s business. Visit environmental for more information.

How Much Does Solar Power Cost And Can You Afford It?

The world needs a new source of energy. The current primary energy source is fossil fuel, which is not only expensive, but also hazardous and will eventually run out. With all these disadvantages, people are now becoming more aware of the advantages of using other sources of energy, such as solar power. But how much does solar power cost?

Using the sun’s radiant energy has some distinct advantages. Such as:

- It is free. As long as the sun comes up, you can tap into its energy.
- It has an unlimited supply. Unless you plan to still be here in a few billion years, the sun will always be there.
- It does not produce pollution.
- It will help you save money.

Solar panels today are very efficient. There are several types of panels out in the market. But the question is how much does solar power cost? The answer to that question can be tricky to answer. That’s because various types of panels can be determined by the efficiency and price. The balance between these two factors may give you the answer to the question.

There are two basic types of solar panels – One is crystalline silicon and the other is amorphous silicon. Amorphous silicon is much cheaper to produce, but is less efficient in producing electricity. Crystalline silicon, on the other hand, is more efficient in converting the sun’s energy to electricity but is much more expensive. To be able to find the right panel for you, here are a few of the solar panels that you can buy on the market:

- Sunsei SE-4000 – This solar panel is a crystalline silicon type that has a maximum power output of 65 watts and is priced at around $650.
- Kyocera KS20 – this is another crystalline silicon type that has a maximum power output of 20 watts. Its price is about $300.
- Silicon Solar – This is an amorphous silicon type that has a maximum power output of 40 watts. It is priced at around $250.
- Sanyo HIP-195BA3 – This is a combination of crystalline silicon and amorphous silicon. It costs about $1000.
- Then there is the do-it-yourself model. These can typically be made for less than a hundred bucks. They probably won’t be as efficient as the professional models and will take a few hours of your time to build it, but they can save you a lot on your initial investment.

To learn more about do it yourself solar power, be sure to read our Energy4Green review.

So how much does solar power cost? By looking at all these figures, the cost of these panels would be at $5 per watt, $10 per watt or $15 per watt. But remember that the numbers shown are the maximum output. The output will vary based on the intensity of the sun where you live.

The History Of Water Pollution

Water is life. About 70% of the human body is composed of water. It is necessary for you to drink clean water. Drinking polluted water is not good for you; it can have an bad effects on your entire body. Sickness such diarrhea and cholera can even be fatal for small children. Plants and animals likewise die from being exposed to polluted water. Go to Enviromental technology for more information.

Let us look at a brief history of later pollution, where it came from, and what are the factors that lead to water pollution.

Ancient times
Water bodies such as lakes, rivers, and streams were the source of water to drink during the ancient times. However, it is the same water bodies where human wastes were deposited. Therefore, in rivers became so polluted that the these ancient cultures needed to construct aqueducts in order to obtain clean drinking water.

The main reason for this water pollution was that human waste found its way to rivers and streams. Cesspools likewise found a way to water bodies and made many people ill.

Medieval Times-1800s
During this period most societies had very little idea of what was bad for you and what was detrimental to the environment. Mercury was commonly dumped into the water supply and most human and farm waste was allowed to run freely into lakes and streams. Most people who lived in cities just dumped their waste and garbage into the street. It probably smelled very bad.

During the latter half of this period civilization made many great strides, often to the detriment of the environment. People even ingested chemicals they thought were good for them at the time that we now know are very bad for you, like Radium and Lead.
The Industrial Revolution of the 1800s saw little care for environmental impact for the benefit of industry.

Many chemicals were pumped into the air and rivers. Most people of the day were not concerned with the impact that their inventions had on the environment. In their defense you could say that nobody had ever given much thought to the fact that the human race could even effect the ecology.

After World War II
In addition to pollutants such as human wastes, fertilizers, leather tanning, and butchering wastes, the emergence of industries and technological factories likewise caused ever more severe water pollution problems. Industrial wastes were freely dumped into rivers, lakes, and streams, polluting the water further and causing large amounts of damage to living organisms using those waters.

1969
In the year 1969, after series of fires on the Cuyahoga River, it was learned that the fires are caused by oil slicks and flammable industrial wastes dumped into it! The government then started the studies that let to the enactment of the 1972 Clean

Water Act.
Even with this act, many people are still unaware of how to protect themselves from chemical pollutants and waterborne diseases. Many large scale cleanups have been ongoing for years.

Present Day
Today, water pollution is still an issue many countries and regions face. It is therefore important for you to know the disease causing agents that may find its way to water bodies. By understanding the damage water pollution can do to your body, you may try to avoid water contamination in your own way. Refer to enviromental products for more information.

Water Pollutants
Human wastes, household chemicals, fertilizers, garbage and industrial by-products are the most major water pollutants. You can help avoid them finding their way to the water you drink by learning how to dispose of them properly or avoiding their use altogether.

Other contaminants include bacteria, viruses, protozoa, and parasites. These contaminants may be caused by human activities (like large scale farming) but there are some other sources in the environment. Tainted water such as this can cause extreme health problems. If you can ensure that the water in your community is clean by avoiding its contamination, you can help avoid bacteria and viruses reaching the water bodies.

Decomposing bacteria are likewise dangerous in large quantities because they will deplete the oxygen level of the water. This is often caused by fertilizer run-off in the form of phosphates and nitrates. The fertilizer causes blooms of algae and when the algae die they decompose.

As they rot the bacteria depletes the oxygen in the water and this often kills fish. If it can kill a fish, how do you think a small child can fight these pollutants if they enter his body?
Acids, salts and toxic metals can pollute the water extensively, making it unfit to drink. Batteries, computer parts and industrial chemicals like PCBs are some of the culprits.

These pollutants are fatal to all animals and most plants. They typically cause internal organs, such as your liver and brain, to fail work properly.
If you cannot access clean drinking water, you and your family will be at risk to diseases and other problems. Help avoid water pollution by learning to respect the environment.

Properly dispose of chemicals, whether household chemicals or industrial chemicals. Being conscious about the environment can save the life of your family and many other people in the world. Do your part in avoiding water pollution so you, your family and everyone else can live a healthy life. Visit environmental for more information.

The Advantages of Using Biofuels

Advantages of Biofuels

Every time there’s an increase in oil prices, people feel it, even if they don’t drive a car. Some suggest we use biofuel to lessen the impact of the rising fuel costs.

But what is biofuel, and how does it differ from fossil fuel?

Biofuel is produced from recycled elements of the food chain, and from plants. It is used in vehicles, and is considered a sustainable renewable source of energy, as compared to majority of the liquid and gas fuels which are used today. Conventional fuels are fossil-based, and there are limited sources available. These sources are depleting fast, and if we don’t find a good replacement, one day our cars will basically stop running.

Types of Biofuels

Biofuels can be used in their pure forms, or they can be blended with other fossil fuels. There are two basic types: biodiesel, and bioethanol. These are currently available on the market and most engines are compatible with them. There is no need to modify one’s existing engine in order to use them.

Biodiesel

This type of biofuel is created using a process that combines oil with alcohol, in the presence of a catalyst, to produce either methyl or ethyl ester. The alcohol used can either be methanol or ethanol. The esters are then blended with the standard diesel fuel, or can be used in their pure forms (100% biodiesel). Biodiesel can replace diesel, or it can be combined with it in such a way that it helps run diesel engines with little or no modifications required. Biodiesel is said to be better for the environment because of the fact that it produces fewer emissions, while at the same time being made from renewable supplies.

Bioethanol

Bioethanol is made by oxygenating various agricultural stocks, such as sugar and starch crops. It can be used in existing engines, although a small quantity of conventional fuel is needed for cold starting. Vegetable ETBE is used at present, as a fuel additive that can enhance octane rating. The vegetable ETBE is a replacement for MTBE, which is made from unsustainable sources.

Controversy

Biofuel might appear to be a promising renewable energy solution, but there are still some issues that need to be addressed regarding its use. While its use may lower the level of carbon emissions on the planet, the production of biofuel has caused debate. The concern is whether crops should be used for fuel or be reserved for use as food.

Hopefully these problems can be resolved. Biofuel might be an inexpensive and renewable source of energy, but people certainly shouldn’t starve because of it.

Recycling Cans Could Help The Enviroment

Food and drinks cans make up around three percent of household waste that is thrown away by households in the UK on a daily basis. Around 75 percent of all drinks cans in the UK are made from aluminium although there are still almost 2 billion drinks cans that are made from steel. Food cans are often called tins because although they are made from steel, they have an ultra thin layer of tin that surrounds them.

If we consider that an average household goes through around 600 steel cans and 200 aluminium cans a year then it isnt hard to imagine the staggering amount of waste that is being generated by each and every one of us annually. We cannot go on burying this waste in landfill sites as the pressure on landfill sites is now nearing capacity and the estimations are that we will run out of space for new landfill sites within the next decade. For more information visit Enviromental technology

At the moment, approximately 80 percent of our household waste goes to landfill sites and as the amount of waste we produce is increasing each year we have to find new and creative ways of disposing of our waste. Landfill is no longer a viable option, not only because there isnt any space, but because landfill sites are not pleasant. There are risks associated with landfill that include the risk of explosion and also a risk of leakage of toxic pollutants into the surrounding earth and waterways which can present a health risk.

Basically, landfill sites are a threat to the environment so disposing of our waste in an environmentally friendly way that saves resources, energy and costs should be a matter of concern for all of us. Fortunately, more and more people are waking up to the idea of recycling. Local authorities also recognise the advantages of recycling and so roadside collections and the number of collection banks where you can deposit waste is on the increase.

Why recycle cans?

Cans are one of the easiest items to recycle and the fact is, each and every can that ends up in landfill is a waste of a valuable resource and heres why. Producing new metal to make new cans depletes the earth of natural resources, such as iron, coal and water to make steel and bauxite to make aluminium and basically it costs more to produce new metal than it does to recycle it.

For example, recycling aluminium not only uses 95 percent less energy than it does to produce new aluminium if we recycle just 1kg of aluminium it saves 6kg of Bauxite. Similarly, if we recycle 1 tonne of steel it saves 1.5 tonnes of iron ore, half a tonne of coal, and uses 75 percent less energy than it does to make new steel. Recycling any type of metal reduces the CO2 emissions released into the atmosphere, reduces water pollution and massively reduces costs in general. For more information visit enviromental products

Cans are also 100 percent recyclable and can be recycled almost indefinitely without any loss of quality to the metal itself. Recycling metal is also a relatively simple process, in fact; it can take as little as six weeks for aluminium cans to be back on the supermarket shelves after collection.

One of the barriers to recycling other materials is the demand for the product. Take plastic for example; it can be cheaper to produce new plastic than to recycle it so there is less of a demand for used plastic. However, there is a great demand for used metal, so much so that there are schemes in operation that will pay you cash for your used aluminium cans.

Another barrier is sorting the waste. Sorting broken bits of glass can be a complex process but sorting aluminium from steel is not difficult. You can tell the difference between aluminium and steel using a simple magnet. If it sticks it is steel, which makes separation of steel very easy as magnets can be used to extract it.

So bearing in mind all the advantages involved in recycling cans, why are any food or drinks cans still ending up in landfill?

How you can make a difference

The truth is that we can all do more to protect the environment if we remember that each can dumped in landfill is a real waste. You can make a difference at home and at work by making sure that your cans are recycled and are not disposed of along with other rubbish. If kerbside collection is not available in your area yet, find out where the nearest collection bank or collection scheme is and deposit your cans there. If we all do our bit we can all benefit from a healthier environment and can preserve the earths resources for future generations.

Home Solar Panels : The Facts

Users can now install solar panels in their homes and reduce their electric bills while preserving nature at the same time Although this technology gives countless of benefits, people are still hesitant to use this mostly because of the installation fee and its functionality.

 

Factors such as site location, house orientation, obstructions to the sunlight and the weather must be considered in setting up solar panels Even when these considerations aren’t optimal, there are solutions enabling you to utilize solar energy to power your home. The effectiveness of your solar panel depends on the amount of sunlight it receives, needing about six hours of constant sunlight the year round Solar panels work best if they are installed in an angle of orientation facing the sun.

Solar electric power, which use photovoltaic cells in converting solar radiation to electricity, and solar thermal energy, which uses the sun’s energy to heat up water are the two types of solar power

A good solar hot water panel system is able to provide an average household with around a third of its annual hot water supply. At first glance, this may not sound much but it can cut back energy cost by considerable amount With the integration of solar panels in addition to this hot water system, plus the addition of other renewable energy sources such as residential wind turbines, they can all work together in providing a renewable, cheap and clean source of energy for your home.

How home solar panels look on the roofs is another concern for some homeowners Photovoltaic panel designs, thanks to the latest technology, are now smaller and more compact. Today, these panels would look like ordinary roof tiles, only with the functionality of a solar panel; they can keep out the sun and rain, and with the ability to convert solar energy into electricity, helps out in cutting back electricity budget

One advantage of solar powered home systems is that energy can be stored in battery packs and chargers, so energy sources are still available even during fall and winter, when there are shorter periods of sunlight.

While it is possible for a household to run completely off photovoltaic electricity using solar panels, this is unlikely in most cases The costs involving the installation for a whole house with electricity from solar energy would be quite high for the average homeowner. It is preferable to use solar panels together with traditional power supplies It is much more cost-effective and energy-saving than depending on fossil fuels alone. You will still depend on fossil fuels but the solar electricity can still provide substantial amount of power, enough to reduce future energy bills
Installation fees can be expensive, but with the constantly rising utility rates, having a supporting source of energy for your home is a good investment. Not only does it protect you from price hikes and power outages, but you will also be protecting nature by using a clean and unlimited source of energy. Solar energy can lower your fuel costs, particularly when used in conjunction with home wind turbine systems.

Use Renewable Energy to Save Money and Planet Earth

You can beat the energy crisis and fire your energy company with residential solar power. Read on to learn how you can create your own energy. Then check out the links in the article for the specific plans you will need to make it happen.

The world is facing an energy crisis unlike any previously seen. We saw what can happen this year when the supply and demand curve gets out of wack. We watched prices of oil, gas, electricity, and virtually all forms of energy double, triple, or even more in price. This problem will only continue to get worse as the demand on energy continues to grow and the non-renewable resources shrink.

So what can off grid living do for you?

You can reduce your monthly energy bill or even eliminate it by using renewable energy in your home. Can you imagine not having to pay the electric company every month? Every person that uses residential solar power also reduces the demand on our non-renewable resources which will make them last longer. A good solar powered home is also more valuable. Imagine how much more you could sell your house for if you could tell the new owners that they wouldn’t have to pay for energy. And most importantly, residential solar power is just plain good for planet Earth.

Now that you know what it does, how do you go about using renewable energy?

The obvious way to use solar energy is to harness the suns rays with solar panels and use it to power your house. You can easily do this without spending thousands of dollars per panel by building them yourself. It isn’t that hard and the links at the bottom will show you how you can get started quickly. Some other ways you can use the sun’s energy is to install solar powered accent lighting instead of wired lights, install a solar water heater, install a sky light or light tube to provide light during the day to a room that doesn’t have windows, and using windows to your advantage to heat your house with the sun’s rays or block the suns rays when you want to keep it cool inside.

Hopefully, this has got you thinking about how residential solar power can help you save money and help save the planet. residential solar power is going to be extremely important in the future as our fossil fuels and other non-renewable resources are used up. Thanks in advance for helping to save the world!

Renewable Energy: Advantages and Disadvantages

If you haven’t heard all the talk about Renewable Energy, you must have been living in a cave for the last 10 years. Even so, if you were in a cave I am sure someone would have told you about solar energy, wind power or hydro power. These are all examples of renewable energy, that are being used in to days world and with the concern of Global Warming, at no other time in our history has this concept been more important. Click for earth 4 energy dvd,

Solar Energy

Every day from sunrise to sunset the sun produces an unimaginable amount of energy, and all you have to do is tap into that energy. You need a solar colletor, which helps you to heat the water in your home or use a Solar cell to convert the sun’s energy to electricity, and if you have ever used a solar calculator I am sure you understand the idea.

This has moved on from the calculator to cells helping to providing power to homes, cars, street lamps, cell phones the list is endless. You will find solar cells helping provide power from the Artic to the equator.

Wind Energy

For thousands of years man has harnessed the power of the wind, it used to be the only way a ship could get across the oceans. You will have also seen windmills that harnessed to power of the wind to grind grains or to pump water. Nowadays we are harnessing the power of the wind to create a clean source of electricity in all parts of the world.

Wind Farms have been appearing all over the countryside, and can produce enough electricity to power thousands of homes. They are surprisingly simple in how they work, the blades of the windmill and connected to an electrical generator through the use of gears and shafts, that mean when the blades turn electricity is created by the generator.

Discover More – Will Global Warming Cause The Next Ice Age?

One major problem in the debate over climate change is a general lack of knowledge on the subject. People usually don’t think about where their electricity, gasoline, or toilet paper comes from. Part of this acceptance comes from the way industry separates products from the production process…When we turn on lights in L.A., we don’t see the plants and coal mines that generated the power…Only those paying careful attention make the connections. Another part of the problem is that we are reluctant to question science, which has such prestige that people rarely stop to question who is funding research and whether that could compromise findings. (Gibson 17)

Most people also don’t understand how the theory of global warming works. They think that a really cold winter is evidence that global warming is a myth. However, scientists that support the ideas of global warming are referring to long-term climate change. Climate refers to environmental patterns over a long period of time. Weather refers to short-lived events, and can have isolated extremes. One of the predictions of many scientists is that global warming will cause more extreme weather: hotter summers, longer droughts, colder winters, and stronger storms. According to their theories, Europe could be tossed into another ice age because of global warming, not turned into a tropical paradise. This is because of the effect global warming could have on ocean currents.

Skeptics will often find any opportunity to attack the views of scientists based on some isolated weather event, or the lack of such an event. If the scientists predict increasing frequency and intensity of hurricanes, skeptics will point out that this last hurricane season was extremely mild, with the only intense storms hitting Mexico. Ultra-conservative commentator, Rush Limbaugh, doesn’t just consider global warming to be a myth; he calls it a hoax and a religion. “It’s got salvation, got everything in it. It has the primary ingredient of every religion: faith. Because none of it can be proved” (Limbaugh 4). Limbaugh also takes issue with the use of the word “consensus” by global warming activists, and is right to do so. “Consensus and science-I got blue in the face saying this-don’t and cannot mutually co-exist” (Limbaugh 4). If scientists had reached any sort of consensus, this would be a dead issue. Most scientists agree that the temperature of the earth has been gradually increasing, but that doesn’t mean they agree on the possible causes or consequences.

A survey of more than 530 climate scientists from 27 different countries showed that 82% of the scientists agreed that global warming is occurring. Only 2.6% said they “strongly disagree.” When asked if current scientific knowledge can allow for a reasonable assessment of greenhouse gases, two-thirds of the scientists disagreed with the statement.

The question most people are most keen to ask climate scientists is probably “do you agree or disagree that climate change is mostly the result of anthropogenic (man-made) causes?” Slightly more than half (55.8%) of climate scientists surveyed agreed, 14.2% were unsure, and 30% disagreed. Interestingly, more scientists “strongly disagree” than “strongly agree” that climate change is mostly the result of anthropogenic causes. The survey clearly shows that the debate over why the climate is changing is still underway, with nearly half of climate scientists disagreeing with what is often claimed to be the “consensus” view. (Bast 4)

The study goes on to clarify that the question wasn’t whether humans have any effect on climate, but whether they are mostly to blame. It’s certainly quite possible that humans are having at least some effect on the climate, but nothing can be proven with any certainty.

Some skeptics believe that mankind is too insignificant and could not possibly have so much influence on the environment. S. Fred Singer is a well-known climate change skeptic. He has been trying to gain support for the theory that climate change is a natural, cyclical process. He believes the earth has a 1,500-year cycle of warming and cooling, with minor ice ages interspersed with interglacial periods. Singer claims that his research shows this cycle going back at least one million years, often with abrupt changes. At one time, Greenland was quite green, with crops and livestock farming. Warm waters were abundant with fish and seals. There were two thriving settlements, but they were eventually lost to glaciers, malnutrition, and starvation. Dairy farmers were even forced to eat their cows. This was due to a 1.5 degree Celsius drop in average temperatures between 1100 and 1400. “Denmark would not re-colonize Greenland until 1721, when the Little Ice Age was losing its grip on the huge island. Today, 150 years into the Modern Warming, Greenland has 50,000 people” (Singer xii). Singer believes that these cycles are caused by solar changes, not greenhouse gases. He is skeptical of activists who “ask society to renounce most of its use of fossil fuel-generated energy and accept radical reductions in standards of living to “save the planet” (Singer 3). While it makes sense to not be swept up in the alarmist propaganda of activists, being unwilling to sacrifice an air conditioner or SUV, if it is truly necessary, seems selfish and defiant.
