In the environment there are many concerns on how to make this a better place to live. One of the biggest issues is our energy and power sources. Green energy is a term used for sources of power and energy that are environmentally friendly. Basically this includes anything that is renewable energy. Renewable energy is considered energy that is constantly being replaced such as wood, vegetable matter, and trash. Green energy's main focus is to use sources that can cut down on pollution. Some of these sources of power and energy are Biomass energy, geothermal energy, hydropower, nuclear energy, solar energy, wind energy and tidal energy. People hope that these will help use more natural sources to produce energy. In several countries you can arrange to buy green electricity. This option does come with a higher cost. Even though this sounds really easy many people are skeptical about these renewable energy sources.

Here are a renewable energy sources:

Biomass Energy- Changing farming wastes, grasses, trees, bark, and even trash into energy by burning it, changing it to gas, or converting it to liquid fuel. You use this energy without even realizing it sometimes. Say you went on a camping trip and you go to build a fire well you have just used biomass energy. Because it plants and trees depend on sunlight to grow, biomass energy is a form of stored energy. Wood is not the only thing that can be used in biomass energy other sources can be corn or waste. One of the most important aspects of this energy is the fact that it can be burned into a liquid which gives us good news for the future because we can use this in transportation. This is very important because one-third of our nation's energy is used for transportation.

Geothermal Energy- This is energy that comes from the heat under the earth's surface. This would mean we would need to drill holes in the earth to reach the molten rock.There are places in the United States where gyser naturally. Basically this energy would mainly use steam in order to produce electricity. This may be one of the slower sources of energy but it would be easier than waiting on a hot spring to come around so you could bath and cook.

Hydropower- This is energy that is produced by water flowing in the rivers and streams. Because this energy is produced on the flow of moving water we would never have to worry about running out of resources. Also we could build reserves with river dams. Hydropower plants are very inexpensive and can generate enough energy to power a whole town, cities, and even the country.

Nuclear Energy- This has to be one of the biggest debatable sources of energy. Though nuclear energy produces no air or water pollution it is among the cleanest of all fuels. There is cost and waste that goes along with this energy. Nuclear plants are running out of storage space. Any the government doesn't want these plants in their areas.

Solar Energy- This energy is in the form of heat and is used for heating purposes. The sun's energy can be used to warm and light homes, heat water, and provide power. Solar energy is
