It is only financially rewarding because it was made politically correct to be an environmentalist. Perhaps. But with the current record market prices for crude oil, you can bet photo voltaics will become a lot more popular and attractive to the general public as solar electricity becomes more competitive with coal/natural gas/oil. While that won't directly relieve the financial burden on pilots, in the long run it could reduce our nation's dependency on petroleum based energy. That's got to be a good thing for US independence from the whims of foreign nations as well as being more environmentally friendly. "next dot-com investment vogue" you may be right but a lot of folks lost a lot of money when that bubble burst. Doesn't that usually occur at the end of most of these popular investment cycles? Personally, I don't see the demand for energy slacking any time soon, so I foresee a much longer investment cycle in the solar and wind power marketplace. |

Electricity doesn't compete with oil and one has nothing to do with the other in the existing, real world. Coal is not oil and US coal comes from the US. Natural gas is not oil and US natural gas comes from the US and Canada. Personally, I don't see the demand for energy slacking any time soon, so I foresee a much longer investment cycle in the solar and wind power marketplace. Until the subsidies run out like last time. -- Jim Pennino Remove .spam.sux to reply. |

Pretty much everywhere in the US, including the oil producing and processing states it is politically correct to be an environmentalist right now. |

On average around the world, sunlight delivers a barrel of oil of energy on every square meter of land every year. At $100 a barrel, a 100m2 roof is receiving $10,000/yr of energy - a quarter of a million dollars over 25 years. With photovoltaic systems we can convert up to 20% of this raw energy directly into electricity. Electricity has little to nothing to do with oil. This is just apples and oranges arm waving. The other minor problem no one cares to address is that contrary to what most people think, peak electricity demand is typically after sundown. -- Jim Pennino Remove .spam.sux to reply. |

With photovoltaic systems we can convert up to 20% of this raw energy directly into electricity. Electricity has little to nothing to do with oil. But it could. Homes can be heated with electricity. Vehicles can be propelled with electricity (including GA aircraft - check Boeing's recent announcement) I don't know what size battery is required to hold enough energy to heat a home all winter, but I know they're getting smaller. The Helios used a hydrogen fuel cell to store electricity for night flight. The photo cells powered electrolysis to separate Hydrogen from Water during the day. At night, they passed the Hydrogen through a fuel cell membrane to generate electricity. |

With photovoltaic systems we can convert up to 20% of this raw energy directly into electricity. Electricity has little to nothing to do with oil. Perhaps not directly, but if the GM Volt* (and hybrid autos) is(are) successful, the replacement of the current crop of gas guzzling SUVs with alternatively powered automobiles could eventually impact oil consumption in the US due, not only to their not using (as much) petroleum, but also due to their increased efficiency (MPG). Add to that the use of solar energy to fuel them, thus replacing/reducing the current requirement for petroleum. If and eventually are a long way away. Roughly 40% of US vehicles are over 10 years old; factor that into the projection of how long it will take before electric cars make a difference in anything once they actually exist. This is just apples and oranges arm waving. You've got to look beyond the obvious to appreciate how solar power can impact oil consumption. If hybrid automobiles provide higher MPG ratings, and solar power spins electric meters backwards, I would anticipate petroleum consumption to be reduced. Don't you agree? Once again, electricity has little to nothing to do with oil. Spinning electric meters backwards won't reduce oil consumption. The other minor problem no one cares to address is that contrary to what most people think, peak electricity demand is typically after sundown. We are both California residents. As I recall, the rolling blackouts** of the beginning of this century occurred during the day primarily due to air conditioning loads. Are you able to cite any statistics that support your assertion that "peak electricity demand is typically after sundown?" I can see where illumination loads might increase, but other loads should be significantly reduced at night, IMO. Like I said, the reality is contrary to what most people think. For about 9 months out of the year, peak electric demand occurs at about 9PM and DST doesn't change that fact. For about 3 months out of the year, i.e. the hot part, you get two peaks, one at mid afternoon and another at about 9 PM. Here's the current demand for California: http://www.caiso.com/outlook/SystemStatus.html Here's some historical data: http://mail.specsol.com/~jimp/caiso.php When the weather starts hitting around 80, the daytime hump picks up. When the weather starts hitting the 90's, the hump gets huge and the blackouts occur. This is consistant for all power producers in the first world and not unique to either California or the United States. So, how many solar plants can one put up before you have idle plants for 8 to 9 months out of the year and where do you get power at night? And once again, electricity has little to nothing to do with oil. -- Jim Pennino Remove .spam.sux to reply. |
