What are fossil fuels? What is the greenhouse effect? How are the two related? Can we reduce our reliance on fossil fuels and lower the emission of greenhouse gases into the atmosphere? Wind and solar power can help lead the way. Learn how state-of-the-art science and engineering can be used to utilize more clean, green energy from both the wind and the sun, right out of thin air.
