Sunlight is solar energy. Sunlight is needed for growing plants that you eat to get energy. Sunlight is also used to make clean electricity. Burning fossil fuels to make electricity pollutes our atmosphere and rivers. Fossil fuels are expensive and limited sources of energy. Nuclear fission is used to create enormous amount of heat and electricity. However, nuclear fission forms dangerous radioactive waste. 

Sunlight offers many ways to get energy. A window can allow warm sunlight into your room. Solar water-heating systems can use sunlight to warm the water for your home, swimming pool and school. Sunlight also warms the Earth and causes wind. Electricity can be made by wind generators. 

Photovoltaic, or PV system use a type of material that converts sunlight into electricity. PV systems can power your air conditioner or a satellite like the International Space Station PV systems are also used to run a calculator, recharge cell phone, or even power lightweight cars.

Sunlight is also changed into electricity by concentrating solar power or CSP systems. CSP systems have mirrors that focus the sunlight. The concentrated sunlight turns water into steam which turns a turbine that is connected to an electric generator. A CSP system usually uses sunlight to make steam. CSP power plants can store large amount of heat. The stored heat is used to make electricity at night. During cloud days, many CSP plants can also bum natural gas to provide the heat that is used to turn water into steam.

Sunlight provides the energy needed to grow plants and make large amount of environmentally friendly heat and electricity. Solar energy can provide power today and for a long time in the future.

UN Reports See a Lonelier Planet With Fewer Plants, Animals

Earth is losing plants, animals and clean water at a dramatic rate, according to four new U.N. scientific reports that provide the most comprehensive and localized look at the state of biodiversity. Scientists meeting in Colombia issued four regional reports Friday on how well animals and plants are doing in the Americas; Europe and Central Asia; Africa; and the Asia-Pacific area. Their conclusion after three years of study: Nowhere is doing well.

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem was about more than just critters, said study team chairman Robert Watson. It is about keeping Earth livable for humans, because we rely on biodiversity for food, clean water and public health, the prominent British and U.S. scientist said. "This is undermining well-being across the planet, threatening us long term on food and water," Watson said in an interview. Scientists pointed to this week's death of the last male northern white rhino in Africa and severe declines in the numbers of elephants, tigers and pangolins, but said those are only the most visible and charismatic of species that are in trouble.

What's happening is a side effect of the world getting wealthier and more crowded with people, Watson said. Humans need more food, more clean water, more energy and more land. And the way society has tried to achieve that has cut down on biodiversity, he said. Crucial habitat has been cut apart; alien species have invaded places; chemicals have hurt plants and animals; wetlands and mangroves that clean up pollution are disappearing; and the world's waters are overfished, he said. Man-made climate change is getting worse, and global warming will soon hurt biodiversity as much as all the other problems combined, Watson said.
