One of the major problems families today face is the price development of home essentials, such as electricity. In today’s world electricity is absolutely essential. Homes, work places, schools are all depending on it; today there is no way we could ever live without it. Now the issue is that the prices of this irreplaceable commodity has started to rise due to global rises in demand and volatility in the global markets for oil. This means that it is more important than ever to think about how we can make savings on our energy bills. And in order to decrease our monthly electric bills, we need to look into alternative energy sources, such as installing home solar panels or windmill power.

Residential power sources are great alternatives to traditional energy. They use solar or wind energy which costs nothing, is recyclable and produces no carbon emissions. The three reasons just mentioned are why lots of people choose to fit wind or energy power units at home. As per recent research, if in the US twenty-five percent of homes are powered by small scale residential power units, possible thousands of regular power plants could be rendered surplus. If this came true there would be significant cuts in carbon emissions and a lot less green house gases the destroy the earth.

Instead of solar power you may want to install home wind turbines that are great if you want to save money on electric bills, save the environment and even our health. These windmills use a free reusable resource, the wind, which will produce energy without emitting any harmful carbon that destroys the ozone. The one time investment in a power unit will last for many years, generating energy for your household. Wind devices work using the wind to turn the turbine that creates mechanical energy. The mechanical energy created is transmitted to wind power generators that convert the energy to electrical power for home use. Energy that is not used immediately can be stored in a battery to be used when there is no wind.

There are two major benefits from using wind or solar power systems in your home. One, you can save a lot of money by using residential power, and two – maybe even more importantly – you can help save the environment. Fitting residential wind or solar units is an investment for the future that will cut your costs for a long time; money, which you can spend on more important things like your family’s needs. There may be another money saving opportunity as well, since some governments offer tax benefits to anyone who installs environment friendly energy sources. It is sometimes possible to also sell electricity if you produce more than what you need. There are also the environmental benefits of using wind or solar power because you lessen the demand of electricity produced by electric power plants that use fossil fuels to produce electricity.

So, not only will you save money, you can also save the environment from the ill effects of carbon emissions.

Many people are starting to change their power to solar power since the finite fuel is starting to run out and become expensive. In actual fact, solar power offers many advantages rather than the fossil be doing well for the environment because solar power does not produce harmful emissions or pollution.

It will charge you lots of money for heating a swimming pool when you decide not to use the solar power. You need electric, oil, gas or some other expensive commodity to operate the electric pump in order to move the water from the pool throughout a heated chamber.

Some have learned that applying solar power significantlextensively reduces their costs energy, regardless of the kind of fuel required for the heat. The water still has to be pumped at least one way from or to the pool, but heating the water with solar power cuts off a large chunk of the bill.

Using large black plastic or rubberized containers, water is pumped out of the pool and into the bladder where it remains exposed to the sun until it reaches a designated temperature. At that time it can be returned, by gravity, back to the pool with the water heated by solar power. If the system is thought through before it is installed, the pumps can be designed to work on solar energy as well. It then provides a heated pool at no operational cost.

Remote Access to Electricity Boost Solar Energy Use

There are several locations to which electric power has not been extended. Additionally, in some applications such as a small fishing or hunting cabins , the use of solar power give electricity where it would otherwise be unavailable.

In some of these areas it is not considered a good investment by the electric company to extend their power lines and the cabin’s owner can’t afford to purchase the setting up. By applying solar power, they can enjoy lots of of the comforts at home without the added cost of an electric bill.

Other convenience that is offered by the solar power is available these days. You can find the flexible and portable panel for various purposes. Since it can be rolled up and carried in backpacks easily, you can use it when go camping. This give solar power. By using this device, you can listen to the radio or charge your cellular phone.

The Unknown Costs Of Using Fossil Fuel

Filed under Fossil Fuels

Go back 30 years and you’ll see that the green movement was positively anti-nuclear. It seems strange that 30 years on some of the very same people are placing their hopes on nuclear power to prevent global warming. It may be that we have no choice other than to go Nuclear but we have to ask the question “why aren’t we placing more emphasis on cleaner types of energy?” Some governments (Denmark is a case in point) have already come a long way in harnessing cleaner and safer types of energy including both Solar Power Systems and Wind farms. They have had great success so you have to ask why other countries are placing their hopes on Nuclear Power?

 The Unknown Costs Of Using Fossil Fuel

The old problems associated with Nuclear Power have by no means gone away. It is still an intrinsically dangerous form of energy and we still have no viable solution to removing nuclear waste! What is keeping us from moving to other forms of energy?

The common argument is that the cost of switching to renewable energy is far more expensive than sticking with fossil fuels. But what of those unspoken costs staying with fossil fuels or moving over to nuclear power?

It is common knowledge that our fossil fuel resources are running out. With the demand for energy set to increase there is only one possible outcome. More price increases! On the other hand, the energy provided by the Sun, Wind and Water is free and will be there for a very long time.

Utilising cleaner forms of energy may not be cost effective at the moment but future developments will surely lead to greater efficiency. For instance, take solar technology. As semiconductor technology moves forward in leaps and bounds, solar panels are becoming ever more efficient. It wasn’t that long ago solar panels could only be used with any effectiveness in warmer climates. Today, we see them being used in many types of environment. Indeed, the science of solar technology has advanced so much people are investing in their own DIY Solar systems. If individuals think it worth their while to build and install their own solar power systems then why can’t it be done on a wider scale.

The financial considerations of sticking with current energy resources is not just limited to supply. We will have to deal with CO2 emissions or the removal of nuclear waste material, a cost that will be with us for many years. Alternative forms of energy like Hydro, solar and wind power are all clean and pollutant free. Future generations will not have to pay for what we do now. The cost of short term thinking is a high price to pay for the future of mankind. Let’s keep nuclear power at a distance. The Sun would be far enough.

Energy Thirsty Planet

The world is an energy devouring place and we need to be researching greener sources of energy to supply that demand. We also need to see cleaner modes of using the current green energy technology that are already in place. We all need to be interested about the impact that is being put on our planet and how the high cost of energy is affecting us. We have an energy thirsty planet and the energy that is wasted every day is a sad state of affairs and everyone should take a look at what they could do to be more moderate in their utilization. We should open our eyes and make ourselves more conservative about our use. There are solutions to these issues but how inclined have people been to execute these solutions at the present.

One of the more popular forms of renewable energy is wind power. The price of the power it creates is becoming really competitive with conventional methods of energy output such as coal and natural gas. Power used to be created by windmills in the past on the family farm for many years. They used to used on the farms to pump water and every farm had one back then. It’s a recognized fact these days that the states of Texas, Kansas, and North Dakota have sufficient wind to provide power for the whole U.S.

Another renewable enegy source that has gotten much press is corn. The ethanol that is formulated from corn is a clean burning energy source and crops can be grown year after year so it is inexhaustible but at what cost. The cost of corn has gone up as the result of this, which is good for the farmer but bad for the consumer. Praire grass has been shown to a far superior alternative to corn. Believe it or not it makes way more energy per acre than corn. Praire grass grows wild. You don’t have to cultivate or tend to it. It is a chemical free crop that just needs to harvested and processed.

Another renewable enegy source we see and hear more of is solar power. There are solar panels that will convert the suns energy into electricity and solar water heating systems to provide hot water. I’ve read about people who have placed solar energy systems on their homes in areas you wouldn’t think it would work, like Seattle. Even though this is a very cloudy rainy area the ROI was quite respectable.

One of the reasons I really like solar power is the fact that it allows people to become energy independent one home at a time. The control of power can be decentralized. Think about it there hasn’t been a lot of money spent on the research and development so costs remain high and the cause doesn’t advance. Corporations want to protect their profits and it almost seems they do anything to make that happen.

We all know that oil isn’t going to last forever. If we don’t start doing something about it now than when. We need to get smart about what we are doing with our energy situation and begin to implement a new energy policy. We need to look to future generations and how it is going to benefit them. Do your part in helping to make renewable energy a reality today.

Different Types of Concentrating Solar Power

Concentrating Solar Power

There are two main types of solar power generation methods used to produce electricity on a commercial scale. Photovoltaic panels, which are the large collections of the systems that you see in small scale on house roofs. Using the heat of the sun as thermal solar power are concentrating solar power (CSP) plants.

We will take a look at the way in which concentrating solar power plants create electricity. CSP plants are capable of producing electricity at a higher maximum capacity than a photovoltaic facility of the same size. They will play an increasingly important role in the move away from fossil-fuel sourced energy to that of renewable energy.

There are four main types of concentrating solar power systems: parabolic troughs, fresnel reflectors, dish / engine systems and central receiver systems. The technology involved with each is proven and either has been or still is in operation around the world with more developments in solar energy in progress to increase global capacity.

Trough systems work by making use of mirrored troughs that are used to focus the sun’s energy onto a receiver tube that is filled with fluid. The heat generated from this process heats the fluid to high levels so that super-charged steam is created. A conventional steam generator is then used to produce electricity.

A trough-based CSP plant typically consists of rows of mirrored troughs placed parallel to each other along a north-south axis in what is known as a collector field. Optimum heat is focused on the receiver tubes thanks to the pivoting nature of the parabolic troughs which track the sun’s movement across the sky. Electricity continues to get generated when the it’s cloudy or after the sun has set thanks to thermal storage. Technological advancements are continuing to prolong this production period in a bid to move to continuous solar electricity production.

One of the largest developments to use the parabolic trough design is the Andasol project in Spain. The surface area of the mirrors used to form the energy collection field of Andasol 3 alone is around 500,000m2.

Fresnel reflectors provide a more concentrated focus of solar energy onto centrally placed receivers. Costs are reduced using this method because the rows are positioned more closely together, there are fewer moving parts and less receivers are required. The receiver is stationary and it is shared by multiple mirrors.

An example of a recently commissioned CSP plant using reflector technology is the Kimberlina CSP plant in California developed by Ausra. This power plant is relatively small at only 5MW capacity, but it paves the way for future large-scale developments.

Dish / engine systems are stand-alone units that contain dish-shaped parabolic mirrors that concentrate the sun’s energy onto a receiver mounted above the dish. From there the energy is converted into mechanical power and electricity is generated similar to the way a mechanical engine runs. Each dish / engine unit has a capacity of around 25kW of solar power and it tracks the sun to ensure optimum power.

An example of the dish / engine technology is the Stirling Energy Systems dish called the Suncatcher that will be used in fields of thousands to form a power facility capable of generating over 500MW of electricity.

Central receiver systems, known colloquially as power towers, is another way to produce concentrated solar power. Looking as though they’re honoring a higher deity, thousands of mirrors called heliostats cluster around a receiver that sits on top of a tall tower. Molten salt is heated as it passes through the receiver and this then makes steam which operates a conventional steam generator. The molten salt can be stored for great lengths of time which means that this type of solar energy generates electricity continuously around the clock.

An example of a central receiver system in development is the Solar Tres power plant being built in Spain. The Solar Tres power plant will be a 15MW facility and it follows on from the successful demonstration power plant known as Solar Two which was located in the Mojave Desert.

One of the crippling problems with solar energy has been the high cost per watt of electricity, but technological advancements are bringing those costs down. Already, concentrating solar power plants hold a huge advantage over the traditional fossil fuelled counterparts in the lower impact to the environment. In fact, one of the only impacts that concentrating solar power plants have on the environment is land use.

Renewable energy continues to grow and with continued support it will eventually become one of the main sources of electricity around the world. Concentrating solar power has proven to be a renewable energy source with still more untapped potential.

What is Solar Power All About?

What is Solar Power?

Solar Power is a form of renewable energy as it utilizes the radiant energy coming from the sun. This is done by converting sunlight into electricity using solar cells.

202px SolarPowerPlantSerpa What is Solar Power All About?

Image via Wikipedia

Solar cells or photovoltaics were invented in the 1880’s by Charles Fritts. Although it did not convert a lot of sunlight into electricity at the time, this started a revolution that continued on to the 20th century. The greatest example is perhaps the Vanguard 1 which was a satellite fitted with solar cells that enabled it to transmit back to earth after its chemical battery was exhausted.

It success prompted NASA and its Russian counterpart to the same with other satellites including Telstar which continues to serve as the backbone of the telecommunications structure today.

The most significant event that stimulated the demand for solar energy was the 1973 oil crisis. Early on, power companies would charge the consumer a hundred dollars per watt. In the 1980’s, it became only $7 per watt. Unfortunately, the lack of government funding did not sustain its growth so the growth of solar energy was only 15% annually from 1984 to 1996. But you can still on your home by checking out house insurance quotes.

There have been a decline in the demand for solar energy in the US but this increased in Japan and Germany. From 31.2 megawatts of power in 1994, this increased to 318 megawatts in 1999 and world wide production growth increased by 30% towards the end of the 20th century.

Next to these two countries, Spain is the third largest user of solar energy followed by France, Italy and South Korea.

There are three basic approaches to get the most out of solar energy. It is namely passive, active and solar photovoltaic systems.

1. In passive, it has to do a lot with the building design. This will enable the building to avoid heat loss so people inside will feel a great degree of comfort with the help of controlled ventilation and day lighting. Homes that apply this will greatly reduce their heating requirements by as much as 80% with minimal cost.

2. Active solar heating is used to convert sunlight into heat which provides space or water heating. Used extensively in Europe, getting the right size will cover 50% to 60% of your hot water heating requirements.

3. Lastly is photovoltaic which converts solar radiation into electricity. This is done by installing solar cells in the ground and the greater the intensity of the light, the greater the flow of electricity. These are available in different sizes and some are installed in consumer devices like calculators and watches.

Some vehicles are now powered using solar energy. Cars although not yet produced commercially compete in the World Solar Challenge which invites competitors from around the world to compete in this annual event in Australia. So to save on your car the best you can do is look at car insurance quotes least expensive. There are also unmanned aerial vehicles and balloons. To date, solar energy has only been successful in passenger boats.

Many of us take the sun for granted and if we are really serious about preserving the environment and reducing our demand for oil, solar energy is just one of the options we have on the table. We have to lobby and convince our government leaders to do more because it is the cheapest means of providing our home with electricity compared to rechargeable batteries, kerosene or candles.
