other hand‚ renewable energy resources are resources that can be replenished within a short period of time (for example: hydropower‚ wind energy‚ tidal energy‚ bio fuels). Hydroelectric Power The most widely used type of renewable energy is hydroelectricity. Most hydroelectric energy comes from the potential energy of dammed water driving a turbine to generate electricity‚ but variations of hydroelectric energy uses the kinetic energy of undammed water. Ultimately‚ hydroelectric power is a combination

Throughout history it is a known fact that humans depend on energy to satisfy basic needs. In order to meet these needs humans have gone to the extent of putting the environment at risk. Air pollution is currently one of the five leading causes of death worldwide and the usage of fossil fuels is a major factor contributing to this. (Future talk: clean renewable energy September 2013). Fossil fuels are finite sources of energy; while the demand for energy will continue to increase‚ there will still

conduct experiments in hopes of finding an alternative to relying on burning fossil fuels for electricity. While companies who believe their alternative is the best choice‚ debate over whose source is the “greenest”. Whether it be biomass‚ hydroelectricity‚ solar power‚ or wind turbines; we must find a new energy source before it is too late. Converting Energy Although many go unnoticed‚ energy conversions occur everyday. A “device” called a transducer converts energy from one form to another

emits. Some energy resources are not extracted from the earth‚ but from nature’s elements or recycled materials. These energy resources are called “renewable” energy resources; renewable energy resources consist of wind‚ hydrokinetics‚ biomass‚ hydroelectricity‚ geothermal‚ and solar energy. On the other hand‚ some energy is extracted from the Earth and the supply will run out one day. This is called “non-renewable” energy resources. Non-renewable energy resources consist of fossil fuels (petroleum

One type of alternative energy is wind energy. Wind energy is a form of electricity produced by wind currents.

Dams are a huge threat to the mighty Salmon of America. Although there are solutions to dams they are not enough to save the species. Salmon are slowly becoming extinct due to dams‚ because dams are cutting off rivers to and from the ocean and preventing them to spawn. Salmon were thriving in the U.S. before hydropower dams were established. Salmon are the most extraordinary fish on the planet‚ they make an extremely long journey that start when they are only a little smelt and finish in adulthood

Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight‚ wind‚ tides‚ plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002)‚ “Renewable energy is derived from natural processes that are replenished constantly. In its various forms‚ it derives directly from sun‚ or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar‚ wind‚ ocean‚ hydropower‚ biomass‚ geothermal

According to National Oceanic and Atmospheric Administration (NOAA) the chinook salmon feed off of amphipods‚ insects‚ barnacles‚ or any other type of crustacean in the young adult age group. Terrestrial organisms can also be absorbed into the digestive system. Adult chinook often times consume smaller fish to fulfill their diet. These chinook fish have a blue-green color located on the dorsal‚ and a large black spot on the node of the tail that appears at an older age. The average size for the chinook
