Physically, yes.

Economically or practically, no.

Yes, there's enough energy in the Earth's wind currents to power everything we do, but there's also a limit as to how many windmills we can stand to build.

If we totally took everything offline and went to wind, the amount of windmills necessary would be far greater than feasible, although we could definitely do it. Windmill farms with thousands of square miles of collective capacity would need to be built, however.

What we should be doing is:
- building wind farms of manageable size
- supplementing with solar
- supplementing with geo
- most importantly: reducing consumption!

There may be a couple other much smaller supplements that we would consider, but the main idea is that we create a diverse portfolio and STOP WASTING ENERGY.

Screw that, I will just use regular nukes alongside TERRA reactors with orbital solar.

I agree with this 100%. I couldn't have said it any better myself.

Short answer: no.

Wind farms only spin in certain areas of certain days. The sun shines, the lava moves, the rivers flow, the tides turn, and the grass grows all the time.

Anyway, Wind should definitely be invested in a lot more. For one, the technology already exists. Its 100% clean, there's enough wind to power the world, and cost improvements are being made. The biggest problem is dealing with power fluctuations, since the wind blows in gusts rather than a constant stream. That'll probably prevent it from ever becoming our main power source, but it should still be used more often as a complementary one.

My bad. Its shining on one part of the earth at a time. But excess energy gathered during the day can be stored for night use.

We could probably do a lot with micro-wind generators as well. They aren't that effective unless they are pretty high up and/or given a hundred yards or so of clearance laterally, but that still leaves quite a few places to put them... the problem is that the cheapest of them are a few hundred bucks. Imagine if every home had built-in solar and wind generators, with geothermal heating... could we get rid of power plants altogether?

Yes, though I'm not sure you could do home scale geothermal very safely (especailly in summer when you are trying to stay cool).

The question becomes how economical is it to do that.

Prices are always changing, but it's not ridiculous.

I'm not sure about the inflation rates fields...

I'd have to believe that these estimates are off.

Looking at the electric vs Geo graph, it is showing that the electric heating system is going to be costing like $350 a month for heating and cooling alone (not counting all the other things that need powering), however, the average american family energy bill is actually only $120 a month. So their math doesn't add up.

Wind power has the problem of being unpredictable, so backup energy generation has to be available for periods of many days. Also, the best place for windmills in the US is the Aleutian Islands, and the next best In North Dakota -- too far from population centers. To solve those problems, some form of extremely cheap energy storage is required, plus superconducting power transmission lines at modest cost.

An elaborate and expensive smart grid is needed to switch the variable wind power in with backup systems.

I live near what was once the world's largest wind farm. Environmentalists sued and succeeded in shutting it down for each winter season, due to bird strikes. I don't see how that can ever be overcome.
