Introduction: Most of the things we use every day, such as our televisions, our computers, our cars and factories, all need energy to operate. What is energy? Energy is the ability to do work, the ability to move or evoke change in matter. Energy cannot be created or destroyed, but it can be transferred between objects and systems. Energy comes in multiple forms and can be converted from one form to another, but the most common forms are kinetic energy and stored energy (or potential energy). Kinetic energy is energy of motion and stored energy is energy that is stored in a system. Fossil fuels are an example of stored energy. Fossil fuels are the remains of prehistoric plants and animals which were naturally transformed into coal, oil …show more content…

The warmer climate is causing the glaciers of Greenland and Antarctica to melt. NASA says that the polar ice cap is melting at a rate of 9% per decade and arctic ice thickness has decreased by 40% since the 60’s. As the glaciers melt they add more and more water to the ocean, causing sea level to rise. Greenland alone holds 10% of the total global ice mass, which when melted could cause the sea level to rise by 21 feet. This leaves millions of people who live near the coast at risk of severe flooding. Warmer temperatures could also increase the likelihood of wildfires and …show more content…

Twenty days of sunshine is the equivalent to all the energy stored in Earth’s coal, oil and natural gas reserves. At present, the most common way to harness the sun’s energy to produce electricity is with the use of solar panels. Solar panels uses photovoltaic cells are mirrors that focus the sunlight in a specific spot to generate the electricity. Solar panels were once very expensive to install but the prices have dropped dramatically in recent years. We can also use the wind to generate power. Another popular way of producing energy from renewable sources if with the use of wind turbines. Wind turbines are devices that has about two or three propeller-likes blades mounted on top of a tower. These blades turn a generator which generates electricity as the wind passes through them. Wind energy is very environmentally friendly and produces no water or air pollutants. Hydroelectric energy uses the current of the water to produce power. Most hydroelectric power plants are located on large dams. Dams are barriers constructed across rivers to control the flow of water. The dam allows a controlled amount of water is forced through the dam. As the water flows through it turns turbines which generate the
