The Five Common Sources of Renewable Energy
Author: Dave Stilman
Energy Source #1: The Sun
The most common renewable energy source is either directly or indirectly from the sun. The energy from solar power can be directly be used for home uses. In fact, many of homemade renewable energy systems are built based on solar power system. The solar power has been widely uses as the alternative power source to generate electricity, and for hot water heating, solar cooling and to power a variety of home appliances.
Energy Source #2: The Wind
Besides the sun, the wind is another commonly use renewable energy source. The movement of wind is captured with the blades of wind turbines to be converted into electric energy, and then turn into electricity via transformers.
Energy Source #3: Biomass
Biomass is a renewable energy source, derived from living organisms such as plants, wood and waste. Although the Biomass has not been commonly used like the sun and the wind, mainly due to the complexity involved. However, scientists are making a good progress toward generating electricity and producing transportation fuels.
Energy Source #4: Hydrogen
Hydrogen is the most abundant element on the earth. It can be easily found many organic compounds, as well as water. Many of us may hear about the new concept of cars which run with water, is the one run on the Hydrogen power generated from water. Unfortunately, hydrogen does not occur naturally as gas, it always combined with other elements, such as it combines with oxygen (H2O) to form water. Therefore, it needs to be separated from other element first before it can be burned as fuel or transformed into electricity.
Energy Source #5: Hydropower
Hydropower is a power generated by taking advantage of gravity when water falls from one level to another. Usually, the kinetic energy of water is captured with water turbines and turns into electric energy to generate electricity.
Summary
The technology improvement has enabled the generation of power from renewable energy at lower cost then before. The above sources are the five major renewable, nonpolluting, and reliable energy sources.

renewable sources:
solar
wind
tide
wave
geothermal, while not renewable, is often classed in this area as it is inexhaustable.
Depends on the household and where it is located. Windy area, use wind power. Lots of sun, use solar power.
solar array would be on the roof. wind generator would be on a tower.
You will need a large array of batteries to supply power when the sun/wind is not available. Alternatively, sell power back to the electric utility company and use power from them during periods of no sun or wind.
if this is an isolated house with no access to the power grid, I’d have a diesel generator for backup.

Non-renewable uses a source that consumes a natural resource in limited supply. (Oil, coal… we can’t make more so it depletes the existing supply.)
Renewable uses a source that can be taken or grown and therefore can be replenished (Sunlight, wood, corn… we can make or take more and it doesn’t deplete a limited supply.)

I am glad you are interested in this question because it is important that we should reduce our reliance on non-renewable resources. Future generations will not thank us for wasting such resources.
Coal and oil are examples of non-renewable energy sources. They are fossil fuels obtained from the ground and were created millions of years ago during a phase in the earth’s development that is over. So as we use these resources less is available for the future. Furthermore burning fossil fuels creates pollution.
Solar panels and wind mills are examples of renewable resources because collecting such energy has little or no impact on its availability for the future.
But it may be worth pointing out that the term “renewable” is confusing. What we really mean is “sustainable”.
Best wishes for a more sustainable future.
talk about all 3 in your intro then in your body paragraphs talk about about each one separately. Some other ideas: cars running on water, solar panels, wind power
hope i helped
How could renewable energy sources be used to meet a household’s needs?
Consider the following issues:
What renewable sources of energy are available?
Which sources could be used to supply a household’s needs? How could each source be used?
Where would the home have to be located to use each source?
What equipment would be needed? Where would this equipment be located?
What backup systems should be included?
For all you smart people out there, please answer all of these questions!
I have NO idea how to start my report on renewable energy sources?
Can someone please help me with an intro and what I should talk about. I have to compare 3 types of renewable energy sources. I already chose geothermal energy but I need two more, which 2 are also the best?
I have no idea how to start it, should I start talking about one source or introduce them all together? HELP PLEASE
Definitions of non-renewable and renewable energy sources?
I need good definitions for both
non-renewable energy source
and renewable energy source.
How are renewable and non-renewable energy sources diffrent?List two examples of each of these types of energy?

What percent of renewable energy sources do energy providers use?
I have to give a speech for a class where i have to persuade the audience to vote for a bill which requires all energy providers in the US to have at least certain percentage of its energy source from renewable sources. I need to know how much they use now, so that i have an idea of how much the required percent would be reasonable. If you know any representative who has proposed a similar bill, please let me know.
