Renewable resource assignment
Hydrogen & Geothermal
How is the energy converted into a usable form of energy?Hydrogen: hydrogen uses water that moves turbines
Geothermal: geothermal uses steam to drive turbines
Hydrogen: Hydrogen is used for producing electricity and is the largest renewable resource used.
Geothermal: Geothermal is used to power electric generators.
What Is It Used For?
BENEFITS
Hydrogen: A non depleting fuel source, little environmental impact, and can be used through out the world.
Geothermal: Geothermal systems does not create any pollution, The cost to build a geothermal power plant is less expensive than building an oil, gas, coal, or nuclear power plant, and No fuel is used to generate this power source.
Disadvantages
Hydrogen: high risk of damaging local eco system, expensive to build a plant, and the risk of a dam collapsing.
Geothermal: Creating a geothermal plant is very difficult and geothermal plants will give off a low amount of nitric oxide and sulphur.
Government plans•Hydrogen: Many governments all over the
world have already set up many dams to create hydro power such as Ethiopia, China, Brazil, Peru, United States and more.
•Geothermal: Although the USA is still skeptical about the idea of geothermal energy the, government of Rwanda is planed to invest in 935million dollars to geothermal energy and plan to generate 310 megawatts to power local towns for seven years.
