Pros & Cons of Solar Power
The sun is a virtually endless source of clean, renewable energy, which should make solar power a logical alternative to finite fossil fuels that pollute the atmosphere and contribute to global warming. So why have scientists been unable to find a way to make solar power cost-effective enough for widespread use?

How to Reduce Global Warming
Here are 10 things you can do every day to reduce your energy costs and your use of fossil fuels, which contribute to global warming.

Cooking Fires Kill Millions
More than half the world’s population—about 3 billion people—cook their meals with wood, dung, coal and other solid fuels over open fires or on primitive stoves inside their homes, and that simple act is killing 1.5 million people every year, according to a report by the World Health Organization. Modern stoves that burn cleaner fuels could be installed cheaply, and would create enormous health and economic benefits.
