The Sun provides Earth with as much energy every hour as human civilization uses every year. If you are a solar-energy enthusiast, that says it all. No other energy supply could conceivably be as plentiful as the 120,000 terawatts the Sun provides ceaselessly and unbidden. If the tiniest fraction of that sunlight were to be captured by photovoltaic cells that turn it straight into electricity, there would be no need to emit any greenhouse gases from any power plant. |

![]() In this diagram, the dark spots signify areas of the earth needed to power the entire planet (assuming a conversion efficiency of 8%). Not much of the Earth's surface, as we can see. - source: http://www.ez2c.de/ml/solar_land_area/ |

It's hitting us whether we like it or not. Let's use it. ![]() Of course, it isn't in any corporation's interest for that to happen, so it won't happen until we remove the corporatocracy. |

I need to see if I can still get the government rebate to install a solar panel here. It's worth doing, even if you're just saving a little money. Fingers crossed you get that rebate ![]() If I wasn't stuck in rented property I'd be doing the same. |

My ex and I had/have 100 acres of land we always planned to go "self sufficient" on
All grand plans for a mud brick house..solar and wind powered...and home schooled kids. ![]() But 25 years ago...it was going to cost over $50 grand just to set up the solar/wind system and we just couldnt afford it. It was still relatively "new" back then...... Nimbin (which I'm sure YOU have heard of) ![]() well whaddayaknow...they're STILL around... http://www.rpc.com.au/ |

My ex and I had/have 100 acres of land we always planned to go "self sufficient" on It'd be pretty awesome to be in that situation I think. Nimbin has so much more to offer than just alternative energy solutions though ![]() |

I'd love to be self-sufficient - and 100 acres is more than enough to do that. My sister in-laws parents are pretty self-sufficient on a half-acre plot of land. The only thing they buy from the shops is meat once a week. The rest they grow themselves, and they have their own dairy too. ![]() The Goode Life....I always aspired to it.....*sigh* |

My only knowledge of solar power is that stupid paddy on TV advertising Everest solar panelled windows or some shit.
"Now be honest, you didn't expect Everest to be doing thta today, did you?" I couldn't give a shit either, amazingly enough. Solar power doesn't bother me, but I don't think about it too much either. |

Ive worked for a Solar plant for the last 14 years, and its a very expensive industry, it was hard for us to get investement for a long time, as the plate could be unstable and degrade over time, this happens to all solar panels, but now everyone is screaming to invest and put up solar, its good news generally, with UK feed in tariffs, its well worth investing in a system to power your home to reduce your bill, and feed the energy back into the grid when you dont need it and get paid.

Solar power has potential. A new technology, called photon enhanced thermionic emission, could lower the costs of solar energy production to the point where it is competitive with oil as an energy source. We also need improvement in batteries or we'll need an alternate energy source for when the sun's not shining.
