UDES of Energy A skier stands at the top of a mountain ready to begin the descent Being at the top of a steep slope gives her potential energy which is the energy an object has because of its position not its motion Once she uses her muscles to push off Earth's gravity will pull her down the slope Her potential energy turns into kinetic energy or energy from movement We use energy all the time in our daily lives Some of the energy we use harnesses the power of kinetic energy Blowing wind and flowing water are forms of kinetic energy that can be converted into electrical energy This electricity can then be used for many different things from charging a cell phone to powering a car We get our energy from other sources too We burn fuels such as coal or oil We generate heat energy from chemical reactions We use panels to collect energy from sunlight Hydroelectric power which is electricity generated from moving water is one of the cleanest energy sources in use However no energy source is perfect some create pollution some are too expensive and some contribute to the warming of Earth and global climate change This surfer depends on the kinetic energy of the wind to push the ocean's water into
