The human activity of burning coal, oil and natural gas is the primary source of carbon dioxide in our atmosphere. Combustion of fossil fuels to generate electricity is the largest single source of CO2 emissions in the United States, accounting for about 38% of total U.S. CO2 emissions and 32% of total U.S. greenhouse gas emissions in 2011.
We have an endless supply of energy from the sun and the wind and there’s no environmental downside to harnessing them! Solar power converts sunlight into electricity using a series of photovoltaic cells connected together to form panels. Wind power converts wind to electricity by means of wind turbines. Both solar and wind power are plentiful, renewable and produce no greenhouse gas emissions.
Solar panels are cheaper than ever before. Small wind turbine systems are available which are suitable for residential rooftop installations. You can obtain tax credits for installing a solar or wind power system. In many states you can sell excess power back to the grid, reducing your monthly electric bill. There’s no better time than now to look into converting your home and your life to use clean, renewable alternative energy sources.
