Solar energy is considered a renewable energy source because it uses the power of the sun to produce electricity and heat. Since the sun isn't going to burn out any time soon, it is a free power resource for the next four or five billion years.
Biopower - The great hope of President Bush, biopower is based on the idea of using organic material to produce fuel for cars, heating and so on. It is better than using fossil fuels, but has some serious disadvantages. Ethanol, for instance, can help replace gasoline, but it produces a ton of smog. Processing organic materials also takes nearly as much energy as it produces in the form of fuel and such. All and all, this is one of the weaker renewable energy resources.
Thermal conductivity, the study of how energy transfer occurs, sounds very interesting. Radiation, or the movement of infrared energy and light traveling across a room, until they absorb, are also important to the second law of thermodynamics as well, because it makes one think about the process of how atoms and energy move from place to place. The concepts of electricity and magnetism can be explained very differently from how Sir Isaac Newton explained gravitational pulls. One learns that lightning is a result of electrical charges, which come about from the transfer of electrons. That makes one think about what is going on to cause the lightning bolt, rather than just running from them!
If you're wondering why the world is still so reliant on fossil fuels like oil, petrol and diesel, and why there isn't more renewable energy used, then perhaps you are about to find out. Consumers like the convenience of petrol and diesel for vehicles, whether for private or public transport. Cars are as popular as ever, despite recent oil price rises, and for most people, the car is the most convenient way of travelling.
For most of us, solar power is the most familiar form of renewable energy. We see solar hot water systems on roofs or bigger panels to supply some or all of a household's power needs. Farmers use solar power to provide energy for electric fences. Most solar power is used by individuals or households, but not in large commercial or industrial buildings. Wind turbines are increasingly being used to supplement fossil-fuel electricity. The turbines cause concerns for nearby residents, with many reporting ill-health associated with the turbines.
Biomass also makes use of waste products that would otherwise be sent to landfill. Waste wood can be burnt as fuel; methane gas from landfill sites can be used as a fuel, and fruit and vegetable peelings and waste can be used as compost in the garden. As global warming increases, and the amount of fossil fuels decrease, there will be more investment and research into renewable energy for both domestic commercial applications.
Because there are no operating costs associated with magnetic generators, power is completely free. This means that an air conditioner can be left on all night and all day without concerns of running up too much cost or harming the environment with carbon emissions. The power bill will be zero and money saved can be spent on things you choose.
Wind power has historically played a big part in US culture. During the 1920s and 1930s, farms throughout the Midwest took advantage of wind power to generate electricity for their lights and electric motors. When our government started actively subsidizing the construction of fossil fuel based power plants and the associated utility lines, wind power fell into decline. Similar to energy efficiency, during the energy crisis in the 1970s, things that were old became new again. Now with growing environmental concerns being expressed globally many people are once reexamining wind power.
