Question

What is the most efficient renewable energy source?

Answer 1

Yes its Hydro electric, but it has been delisted as being environmentally friendly. It kills fish. I think geo-thermal is next up. Wind is third. Solar isn't worth mentioning. I'm measuring efficiency by cost of developping and maintaining the energy source. Every dollar you put in, you get this many watts. And in response to wind being unpredictable, so is solar. There might be clouds in the sky too. I like wind the best, since Geothermal is severly limited by sites. You could tell which is the most cost effective, by what percent of our energy comes from that pareticular source. By the way, we could also make nuclear plant renewable too. I think we can build feeder plants that continously regenerates transuranium. Its not very environmentally friendly.

Answer 2

Most Efficient Energy Source

Answer 3

Water by far. Sunlight is good only for clear days, and for only 6-8 hrs at the most. Plus it is too expensive to buy the solar panels for electricity. Under glass tubing is less expensive but still too short a day light time source. Wind is cheaper mechanically, and probably more hours of production overall. But still depends on sufficient air movement. Water from river flow is the most constant 24/7 production. Dams, are expensive but are multipurpose. Electricity, irrigation, drinking, recreation, flood control. Paddle wheels anchored along rivers or streams also produce continuous electricity and are cheap. They can be smaller or larger. Ocean waves and tides are being looked at as a continuous source also. All water sources of renewable energy are by far and away the most efficient. Water is heavy at 8+ lbs per gal. it does not take very much flow on a lever arm to multiply its effect dramatically.

Answer 5

I never imagined that it was possible to get Free Electricity. I have seen a lot of products offering ways to save on electricity or get free power and I have tried most of them. To my dismay, they are all useless and I just wasted my money trying them. When I saw Power Innovator, I remembered that if someone would have created a Free Energy Device, it would have been Prof Richard Goran the genius that invented the electricity.


And tell you what: this system literally turns my electric meter backwards! Can you imagine how much money I am saving on my electric bill? I hope that many more people will use your product. Thank you so much!

There is a step-by-step video guide online right now that can show you how to reduce your power bill by making your own solar panels.


Take a look at it: http://tinyurl.com/Earth4EnergyRew


Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house.

Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!

Answer 7

This would probably be hydroelectricity. Such plants use the same principles as any other power plant to convert energy of motion into electricity. Solar, is only about 30% efficient, being that it runs on heat only. Wind is unreliable. The river flows ever on...

Answer 8

As per my concern wind is the cheapest source of energy. According to the EIA,the unit price for wind energy is ($0.10 per kW/h) unless it is offshore ($0.24 per kW/h). Nuclear is ($0.11 per kW/h) and solar is still quite expensive ($0.21 to $0.31).

Wind is cheaper mechanically, and probably more hours of production overall.

From overall consideration wind energy is cheap, available, environment friendly and cost effective then geothermal, solar, hydro and tidal energy sources.

Answer 9

if by efficient you mean the one with the highest power yield to our technological level, its hydro power. there's more force in moving water than wind, so water can turn very heavy turbines. hydro power can operate at all times of the day whatever the season or weather, which can affect wind and solar a lot.

Answer 10

From the standpint of cost--hydroelectric power. that is, of course, limited--and already utilized to a great extent.

Of possible alternatives, probably solar--the initial cost is still fairly high--but the operating cost is nil.

Of alternative "portable" energy sources (i.e., for cars) probably ethanol.

Answer 11

The sun doesn't run -just- on heat, it runs on light. However, the sun is only there during the day, which is a bummer. The cool thing about it is that it's free... and no pollution...

I don't know, there are several options that are certainly more environmentally friendly than what we are currently using, for instance, water, wind, sun, ...
