Gilbert Said:

Can u list some different types of renewable energy sources?

We Answered:

The main renewable sources of energy to generate electricity are:


1.Hydro-power (use of water from rivers, dams, tides and ocean waves)

2.Wind energy (using wind turbines)

3.Solar power (using the power of the sun to heat water or produce electricity)

4.Geothermal (using the heat deep under the earth's crust)

5.Ocean Thermal (using surface heat and deep cold water)

6.Biofuel (producing ethanol from organic material like switch-grass, corn and sugar cane husks)

Jeffrey Said:

wat r t various types of renewable energy resources that can be employed for generation of electrical energy?

We Answered:

This is a question with a HUGE answer and there are lots of books out there - Godfrey Boyles Renewable Energy covers all of them. Basically most renewable energy sources come from the sun whether it's solar photovoltaic (PV) panels which produce electricity or solar thermal panels which use the sun's power to directly heat water (over half of our domestic energy use is for heating and hot water - electricity is only a part of the equation), wind power as our weather patterns are all a product of the sun's power, or ground source heat pumps which rely on the grounds ability to retain the heat of the sun. In addition to these are geothermal - which taps into the heat generated by the earth's core, hydro power from flowing water and tidal.
Biomass (burning anything recently living - from wood and straw to rubbish) is not always "renewable" as there isn't an infinite supply of it but it is generally treated as "carbon-neutral" as the carbon realeased into the atmosphere is only that absorbed in the lifetime of the growing matter that is burnt (but it still takes energy to harvest, process and deliver it). For it to be renewable it must be replanted and regrown. Biodiesel is created by fermenting living matter and then refining the alcohol thus created. It can then be used to replace diesel although a lot of older diesel engines will happily run on half and half diesel and vegetable oil. Whilst it might seem like the magic solution to the oil problem remember that we have a limited amount of space on the planet and where food crops are being replaced with fuel crops or, worst of all, rainforest is cleared to provide growing space then not only does it exacerbate the problems of climate change but it also causes food shortages in some of the countries who can least afford them (If we wanted to run all the vehicles in the UK on biodiesel we would require a growing space over that of the area of the UK to grow the stuff). The Centre for Alternative Technology provides a wide range of tipsheet, books and courses on all of these topics and more and operate a free information service.

What types of renewable energy are used in Australia?

We Answered:

I have never ben i Australia but judging by the film footage i saw and the reading I have done it seems to m that solar panels and wind turbines would be the most practical.

great post.
