Fuel cells

The research towards finding an ethanol fuel generator has reached a promising stage. The basis of this research is fuel cell technology. A fuel cell works just like a battery by electrochemically combining hydrogen and oxygen without combustion, to generate electricity. A battery cell requires charging or may drain off after prolonged use. But a fuel cell will continue producing electricity so long as the fuel is continued to be supplied.
The mechanics of a fuel cell include two electrodes sandwiched between an electrolyte. When oxygen is passed over one electrode and hydrogen is passed over the second, it generates heat, water and electricity. The process expels pure drinking water in the form of waste.
Ethanol is the main fuel source for the ethanol fuel cells generators. When fuel substance like ethanol is introduced, the system converts into a generator that provides the power to fuel the car or whatever device you want to run.
Fuel cell technology allows vehicles to run on alternative fuel. Alternative fuels are "green" fuels and they enable vehicles to run for a longer time and at economical rates apart from being environmentally friendly. Experts believe that ethanol will be the fuel for the future. If you add the light fuel cells to the car engine, your car can run just as efficiently as on gasoline. You will also get excellent performance from your vehicle, because Ethanol burns cleaner than petrol. You are also helping the environment as ethanol fuel cell generators give out little or no emissions.

Renewable energy

Renewable energy is growing rapidly, creating thousands of jobs, reducing pollution, tapping American energy sources, and helping consumers and rural Americans. Renewable energy is cleaning up our air and water, improving our health, and protecting our climate for future generations. People do not seem to realise that renewable energy is very economical.
Energy Efficiency
Energy efficiency is currently the 'cheapest' source of renewable energy and another way to shrink the pie. It's easy, when the renewable energy industry is brought up, to picture young, fresh-faced people at the helm of such companies. And while usually that's a bad thing, with methane being a potent greenhouse gas and all, it can be captured and turned into a renewable source of energy. So how exactly do you turn cow crap into energy. Accelerating the introduction of green, environmentally friendly, energy such as solar, wind and wave power is one of the most pressing issues facing humanity in the new millennium, the head of the United Nations Environment Programme (UNEP) told a high-level meeting on renewable energy in Paris, this week.
A community might decide to pursue hydropower instead of wind power because it will produce more electricity than the community needs. This system provides complete protection from power surges and is a whole house backup system. Wind power could be an important part of meeting our commitments.

solar heating

Solar water heating is becoming one of the smartest ways to heat your house, cut down on your monthly costs for heating up water and do your part to help reduce your output of carbon dioxide. This is because solar water heating is a cost effective way to generate hot water to your home using the sun. The sun is responsible for all life on Earth, and generates a tremendous amount of clean, renewable energy that largely goes unharnessed. If, however, this energy could be harnessed, it could go a long way to reducing our use of fossil fuels, and coincidentally our emissions of greenhouse gases. Solar heating can be converted to electricity in the home, as well as a source of heat for water. Solar Water Heating is a simple way of making us of the energy from the sun for your private home.
How Does Solar Water Heating Work?

Solar water heating uses solar collectors or solar panels which gather up the sun's energy and use it to heat up water for your home. The panels will collect the sun's heat and the solar tanks store it for use in the home.

Essentially, there are three different types of solar hot water heaters that can help you to heat your home using the sun: the flat panel collector; the evacuated tube collector and the concentrating collector.

The flat panel collector is the most common and is comprised of an insulated weather proof box that contains an absorbent material which attracts the sun's heat and energy. Flat panels are usually attached to your roof. Very simple flat panel solar collectors are often used to heat a pool that uses solar energy. However, flat panel collectors can also be used to heat your home or provide you with hot water for showers or cooking.

Evacuated tube collectors use parallel glass tubes with an inner and outer tube that absorbs solar energy. The advantage of evacuated tube collectors is due to the fact that the outer tube is evacuated, does not contain any air, there is a minimum amount of heat loss through radiation. Concentrating solar collectors use troughs that concentrate the sun's energy onto an absorber tube which will contain a heat transfer fluid.

solar power

Convenience is another factor to consider when looking at solar power versus generator power. Solar power is much more convenient than generator power.
Solar power may be less convenient to purchase and install, since it is not as widely available as generators. This is due to the currently small market for solar power. As the market increases, however, this will be less of a problem. Solar power systems have no moving parts to wear out or need lubrication. Once installed, solar power requires little attention. The user can almost forget it.
Generators are widely available, so convenient to purchase and install. Convenience decreases after installation, though. A generator must be monitored frequently to be sure sufficient fuel is available. It must be refilled often when used as a regular source of power. Fuel must be ordered and delivery taken - or fuel must be hauled by the owner. The system must be serviced twice a year. This servicing will include filter changes, an oil change, a tune up, and complete inspection of the entire unit. Worn parts must be replaced.

Tidle power

New renewable energy sources are popping up all the time and are coming more and more into our consciousness as well as being firmly set as something to address on the new Government's agenda. There are many forms of large scale renewable energy that countries around the world are looking into but here's a look at tidal energy and how it's progressing.
Tides are the rising and falling of the ocean's water level and are the result of the gravitational pull on the Earth as it rotates created by the sun and moon. The main reason that tidal energy is something being considered by Government's worldwide is that the tides never stop. Harnessing their energy would mean a constant and predictable source but at the moment there are very few places in the world that do.
The world's first tidal power station, Rance Tidal Power Plant, opened in France in 1966 and after over 50 years it is still the world's largest. The Annapolis Tidal Generating System run by Novia Scotia Power is the only tidal power station in the USA and is situated on the Annapolis River. Here the plant takes advantage of the highest tides in the world at the Bay of Fundy to generate power. The world's third largest plant is the Jiangxia Tidal Power Station however, South Korea are currently in the process of constructing numerous tidal plants that will each generate double the amount of energy than any current tidal power station!
There are other forms of technology that can harness energy from the tides other than the more traditional techniques. A relatively new technology uses open-centre turbines that are placed on the sea floor, this recent invention is the first turbine that will actually sit below the ocean's surface and unlike previous technologies don't require a dam to be built. Their design minimizes impact on the environment and they were first deployed in the Bay of Fundy to mixed success and will be tested further next year.

renewable source energy

The rising levels of pollution around the world are a definite cause for worry. If something is not done quickly, then there is a genuine danger of us making the world totally uninhabitable for the future generations. This is where clean renewable energy sources come into picture. A lot of research is going on around the world on the topic. Several alternative sources have emerged in recent times and the good news is that they are being increasingly used in different parts of the world.

Solar energy is one such renewable source of energy which is being increasingly used these days. By tapping the immense energy of the sun's rays electricity is produced by photovoltaic panels. You can now reduce your energy bills substantially by using solar energy. These days even many industries are using solar power for running their operations.
Wind energy is another area where a lot of research is going on nowadays. Wind energy is cheap, renewable, and available in abundance. Apart from onshore wind turbines, these days offshore turbines are also being used in several countries to generate wind power. Domestic wind turbines too have started making their appearance. In fact, with a little bit of effort and investment of your time and energies, you too can build a domestic wind mill on your own.
Generating energy from waste or garbage is another field where rapid progress is being made nowadays. Several governments have set up plants specifically for the purpose of generating energy out of waste these days. These clean renewable energy sources have the potential to completely transform our planet for the better, if they are used in the proper manner. With technology advancing at a rapid pace, several new breakthroughs in clean energy sources are expected in the near future. All these developments augur well for the environmental health of our planet.

Fuel cell

Fuel cell technology and research has come a long way since the early days. Fuel cells used to be large, bulky, and expensive to build and maintain. But this new generation is any but big and bulky. In fact, it is now possible to build fuel cells small enough to power nearly any small household appliance.
 Fuel Cells for Everyday Use
With the development of these new small fuel cells could come a major evolution in portable power sources for small household appliances. Because fuel cells can now be made that are small and lightweight, they can make nearly any small appliance in your house cordless. I'm sure you can easily see the advantages of that!

solar power

The solar power versus generator battle includes the matter of efficiency, too. Which is more cost-effective? The facts seem to point to solar power. Solar power is received in through the panels, free of cost, and stored in batteries. It is ready for use when needed, but in times of reduced usage, the power remains in storage.
Generators run constantly, regardless of the amount of power being used at a given time. As they run, they consume costly fuel. When power usage is reduced in bright daylight, generators must continue to run.

renewable energy

The sun is our most powerful source of energy. Sunlight, or solar energy, can be used for heating, lighting and cooling homes and other buildings, generating electricity, water heating, and a variety of industrial processes. Most forms of renewable energy come either directly or indirectly from the sun. For example, heat from the sun causes the wind to blow, contributes to the growth of trees and other plants that are used for biomass energy, and plays an essential role in the cycle of evaporation and precipitation that makes hydropower possible.

Hydroelectric power

 It is a energy that can be easily get from running water.Its energy production is so high that it can even be used in a house or a big mill.There are more than million hydro-electric power stations.It can also be used to run turbines.They can give a big amount of energy at affordable prices.It doesnot need uranium,oil or other fuels for its set up.It also gives electricity of low price and more portable energy provider.Pollution produced by Hydroelectric power is minimised.Manpower needed for its setup is very less.It stations set up depends upon the size of the river.As it is a renewable source of energy,so it can be get at any time of the day and night also.These can be put into use for a long time once it is set up as it is easy to set and very low maintainance cost is needed in this.It gives useful energy in a large amount and provides evergy all over the world.

Hydroelectric power

There are various types of renewable sorces of energy which add solar, wind, and water. It saves people”s money spent on energy. These are healthy sources for environment as they are pollution-free, and increase people's house value. Energy Sources are long lasting and will not run out like the exaustible power sources that is fossil fuels. It also gives some economic benefits to rural areas where electricity problem is at great heights. Parts for making them are available in market easily. It deals in long term to make an investment in renewable energy.The parts used in this donot need more maintenance as they are not operated by conventional fuels. It helps saveguard the planet for our future generations.It reduces the cost of energy and also the environmental by unhealthy issues which include the greenhouse gases, toxic wastes and other chemical pollutants caused by the conventional power plants by which our planet is typically safe making it much cleaner. The best advantage about their usage is that the sources do not leads to global warming. These make us realize that these forms of energy are worth if they are brought to use.

The biggest apprehension for many people are sliding towards hydro electricity plants is that it is a renewable energy that means it can be replenished. Hydroelectric power brought the industrial revolution in the powering factories where iron and steel are dealt with. It is also known across the world as a catalyst in the utilization and development of renewable energy.Canada is known to be at the top in the use of hydroelectric power. Hydro power has a wide adoption and are important. Hydroelectricity producing projects are once constructed,the energy produced is cost effective and healthy. As contrasted to other power sources pollution produced is minimal. Hydroelectric power production uses falling water to generate electricity which is easy to get anyywhere and set the plant. People donot have to stretch their thinking too far. Hydroelectric power is so cheap that if there are more water and dams,it could lower our nation's energy costs at a great quantity. Site of a hydroelectric plant is easily available at most of the places.Most of the large scale hydro power systems are associated into dams and reservoirs.
