Non-renewable energies are effecting our environment for the worse. The search for new energy source such as alternative energy sources are starting to become an important factor in the human society. Solar power energy is one alternative energy source often over looked that our society should begin using. Solar power energy works like this‚ “When sunlight hits a solar panel‚ it makes electrons in the silicon move around. (Electrons are teeny tiny specks—they’re way too small for us to see‚ even

Today‚ many countries are depending more and more on nuclear energy to produce electricity. Although‚ nuclear energy can bring many benefits‚ such as nuclear fission‚ which releases no carbon dioxide‚ it also brings many risks to many countries that use nuclear energy. This was proved‚ in many disasters that nuclear energy caused years ago‚ like the Chernobyl Disaster in April 26‚ 1986‚ which was said that‚ “the radiation released was to be 200 times that of Hiroshima and Nagasaki nuclear bombs

Personally I would start with the first recorded tsunami‚ which if wikipedia is right was as far back as 426 BC. To me that is shocking because I hadn’t heard of Tsunamis until late 1990’s‚ so the fact that this isn’t a "new" phenomenom is a little surprising to me. Then I would have a small paragraph on what causes tsunamis. Then I would decide since you only have 2000 words if I want to focus on the dollar destruction‚ the lives destruction‚ or the infrastructure destruction. You may be
