Question by Eleni del Egeo: What is the percentage of alternative energy sources in your country?


Are alternative power sources (solar energy, wind power, etc) popular in your country?
What is the percentage of their use?

Best answer:

Answer by campbelp2002
On the order of 1% in the U.S. In some states, like California and Texas it is higher, but still less than 5%. I am not counting hydroelectric power in that because it is a traditional source, although totally renewable.

According to the source below, Denmark gets almost 20% of its electricity from wind.

Question by Anonymous: What are three renewable alternative energy sources?


I need help on this. When u answer can u be thorough about why the 3 alternative energy sources are renewable please.

Best answer:

Answer by Dave
Wind, solar and tidal (or wave) power.

They are considered renewable because no matter how much wind or sunlight or how many waves you use, you’ll never consume it all. Petroleum products like oil and natural gas are not renewable because there is a finite amount of it in the ground. When it’s gone, it’s gone.

It may not be windy, sunny or wavy every day, but there’ll always be more.

Question by rcdreamz: What alternative energy sources would you recommend for Third world countries?


What alternative energy sources would you recommend for Third world countries to acquire instead of nuclear technology?

Best answer:

Answer by ron853211
That is very difficult because they have no money for initial investment. And it cannot be demonstrated that investments in solar, wind or water can ever pay off for 3rd world countries. Essentially, someone must “give” them something, or they will never get off the ground. Sad, but true, I’m afraid…

Question by Fletcher: How efficient are fossil fuels compared to alternative energy sources?


By alternative energy sources I mean things like solar, wind, nuclear, geothermal, hydroelectric, etc. I want to see how efficient they are, not really paying attention to how polluting they are.

Question by EmoStyleGirl: how do alternative energy sources work?


this is a science hmw that is due on tuesday, and i need help plz!
the topic is Alternative Energy.

So I need to know how alternative energy sources work. that is the question i have the most problems on… if you wouldn’t mind I would appreciate a sentence or two on these two questions about alternative energy sources.

Can we use them to generate electricity?
and
How can we use them to generate electricity?

Answer by Matthew B
Alternative energy is about renewable energy. Energy sources such as solar thermal, wind, geothermal, tidal, and hydro-electric can be reused. Once set up there is lower running costs. Most of these sources are converted to electricity for distribution and use. These systems convert mechanical energy into electrical energy.

Compare this with raw materials costs like, coal, gas and nuclear including above average inflation prices increases.

Question by E.: How does solar Energy compare to other alternative energy sources?


Is it better or worse than majority of the other alternative energy sources? If so why?

Best answer:

Answer by nitebearer
It is actually a nice form of energy. Unfortunately it has a few negatives
1: Only available during the day (unless power produced goes to storage)
2: Only produces full power on sunny days
3: Requires a large array to supply decent amount of power, requiring larger area for the array.
4: Storage facility (so you have power at night) requires space and maintenance.

This is where wind is claimed to be better but if the wind dies the generator stops, but if wind it operates day, night, cloudy or rain and usually at night puts power back into the grid and can do so during the day while you’re at work.

Solar is great for low power demand items like lights (you can now get a variety of low power lighting systems) and chargers for cell phones and other devices. To run larger devices you need a large array and power converters and a power storage (batteries) with enough capacity to supply the demands of your devices. The whole system can be quite expensive but yes in the long run could save you money. Note that storage devices require weekly maintenance and checking for problems as they die after a few years so you have to replace them.

I made this video for my class, Web 2.0. It is about Alternative energy sources, how they work, and how they are used today. I hope you like it!

Solar power is one of the most used unconventional sources of energy today. Not only does it generate energy for free, it’s clean and virtually.

Like most individuals you most likely know that now more than ever we have to find different energy sources. Solar, nuclear and wind power are all viable.
