Transcript of Renewable/ Non-Renewable Energy

Renewable/ Non-Renewable
Energy Renewable Energy Bioenergy The organic matter that makes up plants is known as biomass. Biomass can be used to produce eletricity, transport fuels, or chemicals. the energy that comes from Biomass is know as Bioenergy. Biomass produces 50 mega watts of energy per station. Solar Energy Solar energy is the most common used renewable energy source. Solar energy can be used directly for heating and lighting homes. How solar energy is collected is by solar panals. solar energy produces 11 mega watts of energy per station. Most of the renewable energy sources reli on the sun. Non-Renewable Energy Did you know that in one second the sun produces enough energy to meet the needs of the entrie earth for 500,000 years Renewable: Defentions: Capable of being replaced by natural ecological cycle or sound management practices. It is not at a limited supply. Non-Renewable: Energy sources, such as fossil fuels, that are replenished at a much slower rate than they are used. Energy: Cannot be created or destroyed in any process but can only be converted from one form into another. Wind power Wind is captured by wind turbines Hydrogen Hydrogen is found in many diffrent organic compounds. Hydrogen is th abundant element on earth. Its always combined with othe relements. Once Hydrogen is seprated from another element, it can be burned as a fuel or converted into electricty. Geothermal Geothermal energy taps into the earth's internal heat, for a varitey of uses, such as eletric power production, and heating and cooling of buildings.` Geo thermal energy creates 750 mega watts of energy per station. Renewable energy Most renewable energy comes from light, directly or indirectly. Out of all energy used 4.65% is renewable energy Hydroelectric Hydroelectric is amreicas leading renewable energy resource. hydroeltric is the fouce of falling water. When water falls from the lake above the dam, the fource of the water pushes the tubine blades, which are connected to a genorater that produces electricity . After the water has passed through the turbine the water returns to the river on the other side of the dam. Non-Renewable energy Non-renewable energy resources are natural. Coal, petrolium, oil, and natural gas are examples of natrual gases. they all come from somewhere deep in the ground.
Air: earth's respiration and plant and animal respiration
Animals: reproduction
Forests: reproduction and germination
Grasses and Plants: reproduction and germination
Microbes: sexual and asexual reproduction
Nutrients (carbon, nitrogen, phosphorus, sulfur, etc.): decomposition of plant and animal wastes followed by biogeochemical cycles
Soil: Earth's sediment cycle
Sunlight: activity at the Sun's core
Water: biological reactions, including respiration
Wind: climate, tides, and weather
Coal: mining for energy production by burning
Land: development for population expansion
Metals: mining for industrial use
Natural Gas: extraction for energy production by burning
Nonmetal Minerals: mining and other extraction methods for industrial use and other commercial uses
Petroleum: extraction for energy production by combustion and industrial uses
Uranium: nuclear energy production Renewable and Nonrenewable Resources Non-Renewable resources of energy Fossil fuels are mainly the non-renewable sources of energy. they come from animals anf plants that have died over many years ago. When they decompose, they create energy like oil, coal, and natural gas. Coal and oil are our mostly used resources and we are using them faster than they are being produced. Over the next 40 years or so, we will have to try to find new ways to produce energy. Alternative energy sources Sun, wind, moving water, plants, and animals are all examples of the alternative energys that we will have to start finding new ways of using to create gas and electricity. The fossil fuels are creating global warmaing like pollution. 85% of the United States uses fossil fuels to power things like house hold items of cars. Because we use so much, we will run out and have to still produce that sort of energy so they have come up with alterate energy sources. We rely on other countries to supply non-renewable sources of energy to us. So, we need to invent new ways to make electricity and gas. Alternative energy sources have gotten popular/ we need to develope renewable energy sources. Something that doesn't pollute and add on to global warming... Oil Oil is also known as petroleum. It is found in underground rock formations. It is mixed in with other chemicals to make gasoline, sulfer, oxygen, and nitrogen. Non-renewable sources Resources like oil or minerals are formed over millions of years in the earth. Earth can replenish non-renewable resources but it takes eons to make the fossil fuels with raw earth materials. By: Brooke Brown
