Electricity generation is the leading cause of industrial air pollution in the U.S. Most of our electricity comes from coal, nuclear, and other fossil fuels power plants. Electricity generation is responsible for: 38% of the nation's carbon dioxide (CO2), a greenhouse gas and major contributor to climate change. 66% of the nation's sulfur dioxide (SO2) when combined with rain water, creates acid rain. 40% of the nation's mercury contributes to contamination of soil and waterways. 25% of nitrogen oxides (NOx), which react with sunlight to create ground level ozone and smog.

Households consume 1/5 of total energy in US American households used approximately 866- kilowatt hours per month in 1999 costing them $70.68. The typical U.S. family spends almost $1,500 a year on utility bills. About 60 percent is in the form of electricity; the remainder comes mostly from natural gas and oil.

One of the most valuable and environmentally-friendly sources of energy is solar power. How do solar panels work? The sun is collected by the silicon that is located on these panels. The UV rays make the electrons that are located in the silicon move around. As this movement takes place, the energy begins to form. After this occurs, the energy is then moved out of the panels and into a battery or other kind of collector.

1. Saves you money After the initial investment is recovered, energy from the sun is practically free The savings are immediate and for many years to come. 2. Environmentally friendly Solar Energy is clean, renewable (unlike gas, oil and coal) and sustainable, helping to protect our environment. It does not pollute our air by releasing carbon dioxide, nitrogen oxide, sulfur dioxide or mercury into the atmosphere like many traditional forms of electrical generations does.

3. Independent/ semi-independent Solar Energy can be utilized to offset utility-supplied energy consumption. It not only reduces your electricity bill, but will also continue to supply your home/ business with electricity in the event of a power outage. A Solar Energy system can operate entirely independent, not requiring a connection to a power or gas grid at all. 4. Low/ no maintenance Solar Energy systems are virtually maintenance free and will last for decades. Once installed, there are no recurring costs. They operate silently, have no moving parts, do not release offensive smells and do not require you to add any fuel.

As the wind flows past the rotors of a wind turbine, the rotor spins and drives the shaft of an electric generator. Running the wind power along with adding the utility grid costs can range from $15,000 to more than $50,000 per mile, depending on terrain.

1. Saves You Money Wind energy is one of the lowest-priced renewable energy technologies available today, costing between 4 and 6 cents per kilowatt-hour Wind energy systems involve a significant initial investment, but can be competitive with conventional energy sources when you account for a lifetime of reduced utility costs 2. Good For The Environment Wind energy is fueled by the wind, so it's a clean fuel source Wind Energy is widely distributed and also reducing toxic gas emissions.

3. Wind Generating The World By 2020, wind-generated electricity is projected to satisfy the residential needs of 195 million Europeans—half of the region's population. The United Kingdom is requiring an investment of over $12 billion in off-shore wind farms that should satisfy the residential electricity needs of 10 million of the country's 60 million people. Tiny Denmark, which led Europe into the wind era with the development of its own wind resources, now gets an impressive 20 percent of its electricity from wind. Germany overtook the United States in terms of wind-based generating capacity in 1997. Now Spain is close to overtaking the United States as well.
