essay

1. Wind power generation pointed out as kind of energy with the fastest growthrate in the world today, why the Indonesian state has not implemented fullyhydro(PLTN) ?

Answer:statistical areas in Indonesia are less fully support because it does not allareas / regions in Indonesia potential. only in the tip of Sumatra and theeastern area of Indonesia that coverage will very much lah. that is why theIndonesian state has not fully switched to nuclear power plants. and onemore thing the wind power is not stable in all regions Indonesia.

2. to Indonesia with an estimated average wind speed - average about 3 m / s.whether the right turbine in use in Indonesia?

Answer:small-scale turbines more suitable for use in Indonesia, the difference affectsthe capacity of the initial minimum speed requirement (cut in win speed) thatneed large-scale turbines operate on the cut to win speed 5m / s while thesmall-scale turbines can work 3m /s.

soal 1in areas where there is only allowing its nuclear power plant in Indonesia?and whether nuclear power could be applied in Indonesia we know the range ofissues existing nuclear radiation?

Answer:indeed there are still cases like that. because the country who can build a nuclear

power plant must have a high stability both political and other. foreign parties mustlimit, because there is an international nuclear agency IAEA name, and it is not onlytaking care of one country alone but lot.

soal 2We know the construction of PLTN in Indonesia is a lot of Controversy, like where doyou personally respond to this?and here you think TV is more dangerous radiation from the nuclear radiation, how?

Answer:

Radiation tu TVs larger than the nuclear radiation. imagine if you watch TV, howmany hours you are stronger? It can damage organs of the eye.while waiting for the other alternative energy, while the war to the WHO Thosecountries want to boycott us. prevented positive creative people. may not dunkz!God created the earth and sky tu emang studied in order to make us more Cautiousand Recognize the Greatness of God! !

Questions

1.What is the meaning of biogas?


29/59

2.What is the advantages of biogas?

Answers

1. Biogas is gas produced by anaerobic activity or fermentation of organic materials

including: human and animal excrement, domestic waste (household),

biodegradable waste or any organic wastes are biodegradable in anaerobic

conditions. The main content of the biogas is methane and carbon dioxide.

2

1. Biogas does not destroy the balance of carbon dioxide caused by deforestation

(deforestation) and destruction of land

2 Energy Biogas can serve as an energy substitute for fossil fuels that would reduce

atmospheric greenhouse gases and other emissions.

3 Methane is a greenhouse gas whose existence duatmosfer will increase the

temperature, by using biogas as a fuel it will reduce methane gas in the air.

4 Waste in the form of animal manure and human waste is material that is not

bermanfaaat, even menngakibatkan a very dangerous poison.
