How can I put the sun’s energy to work for me?
Step outside on a summer day in Texas and you'll experience the power of solar energy! The technology for harnessing the power of the sun to produce electricity has improved, but it may not be cost effective yet for your home. Solar energy devices can, however, power your outdoor lights and heat the water in your home or swimming pool. And you can benefit from passive solar energy by opening the shades in the winter to let the sun warm your home. We can also learn from our grandparents and use a clothesline to dry our clothes.
