Solar Energy Facts

The sun is the main source of almost all energy on earth — even fossil fuels (coal, gas and petroleum) began life as plants whose energy came from the sun millions of year ago. Of course, the sun is also the original source of most renewable energy sources too — solar, wind, hydro — because the sun actually gives energy to the atmosphere, which creates wind, rain and ocean currents.

Quick Energy Efficiency Tips & Facts

Here are some fun facts about easy things we all can easily do to save money on our heating bills.

• If every American household replaced one of its incandescent light bulbs with a compact fluorescent bulb, it would save the same amount of energy as a large nuclear power plant produces in a year.
• You can save 10 percent or more on your energy bill by reducing the air leaks in your home.
• By strategically placing trees, shrubs, and other landscape structures to block the wind and provide shade, residents can reduce the energy needed to keep their homes comfortable during heating and cooling seasons.
• Only 10 percent of the energy consumed by an incandescent bulb produces light; the remainder is given off as heat. Technologies developed during the last 10 years with fluorescent lighting can help cut lighting costs 30 to 60 percent while enhancing light quality and reducing environmental impacts. And LED lights are about to even beat that.
• Recycling an aluminum can saves 95 percent of the energy required to produce a replacement aluminum from bauxite.
