5 different renewable energy resources
biomass, solar, geothermal,hydroelectric,wind
where does biomass originate from
any materials that come from plants or microorganisms that were recently living
where does solar energy originate from
the sun
where does geothermal electricity come from
within the earth
where does hydroelectric energy come from
flowing water
where does wind energy come from
captured by wind turbines
How do we obtain wind energy
wind blows the turbine blades making them spin creating kinetic energy, the blades turn shaft which turns the generator producing electricity
how do we obtain hydorelectric powe
water goes into a dam, the moving water spins a turbine creating kinetic energy which is converted to electricity through a generator
how do we obtain geothermal energy
water is pumped deep into the earth, meets the mantel which boils the water to create steam to turn the turbine, drives a generator which produces electricity.
biomass advantages
can be stored and used when needed, releases less harmful pollutants than gasoline, uses materials that would usually be discarded
biomass disadvantages
growing crops for biomass requires a lot of land and pesticides, land could be used for growing food, pesticides can pollute
wind advantages
can be very efficient and cheap in places with steady winds, its clean and no pollutants
wind disadvantages
wind is inconsistent, not a good source of energy in all locations, dangerous for bats and birds
hydroelectric advantages
energy is inexpensive to harness, available resource because rivers are everywhere, reliable because engineers control the flow of water.
hydroelectric disadvantages
damming a river causes a great environmental impact for people, plants and wildlife, dependant on rain fall to fill reservoir, expensive to build a dam
geothermal advantages
clean, does not require another fuel source to produce into the air, does not emit any harmful pollutants into the air
geothermal disadvantages
not a wide spread of source of energy, high installment costs to build power plants, not easily transported
solar advantages
relatively simple technology, little maintenance, reliable and quiet, free energy after purchasing soar panels
solar disadvantages
energy cannot be created at night, cloud cover reduces power,works best if at the optimal angle towards the sun, only converts 20% of the sun's energy to electricty
