The Earth Policy Institute reports that replacing incandescent light bulbs with CFLs (compact fluorescent light bulbs) and LEDs (light-emitting diodes) is the easiest and and most cost-effective way for households to reduce carbon dioxide emissions and increase energy efficiency.*
On a larger scale, renewable energy comes from any natural sources that are constantly and sustainably replenished. Energy that comes from wind, sun, water and plants will create a cleaner environment including creating better air quality, curb global warming and reduce the use of fossil fuels.**
Wind energy is an affordable renewable energy that is completely pollution-free. American wind generates enough electricity to power 10 million homes and federal researchers estimate that wind energy could power 30 percent or more of the country’s electricity needs.***
Another renewable energy is solar energy, a resource that has made technological leaps in the last few decades, making it much more cost effective for the average consumer. Sunlight is free, available to everyone and produces no emissions including those that cause global warming.****
