For your abundant extra cash, Turbo Encabulators make even more hard sense than carbon credits.
The vast profits from AGW are rolling in.
How long do you think it takes to save the energy required to make a photovoltaic converter? You’re trying to save energy, right?
Luboš Motl at The Reference Frame has the story – RICS: Solar panels pay back in 100 Years (almost).
More precisely, it is actually 200+ years: the panel costs up to USD 10,000 and saves USD 50 per year. For example, you will need about fourty 10-Watt panels that cost about USD 250 each to get somewhere. Wind energy scored comparably badly while the insulation was the winner.
The story of the AGW photovoltaic rip-off is here.
The capital we are investing to save the Earth should be spent on nuclear energy, instead; if we were really interested in saving the Earth.
PS: The PV cells should last a good 30 years.
[In edit: The manufacture of photovoltaic converters is extremely energy intensive; if the PV cell can only repay 1/6 of its purchase price in its useful life, the distinction between energy payback and capital payback becomes immaterial; both are negative]

Solar panels are one of the least cost-effective ways of combating climate change and will take 100 years to pay back their installation costs, the Royal Institution of Chartered Surveyors has warned.
In a new guide on energy efficiency, Rics said that roof panels for heating water and generating power are unlikely to save enough from bills to make them financially viable in a householder’s lifetime. In the case of solar panels to heat water for baths and showers, the institution estimates the payback time from money saved from electricity and gas bills will take more than 100 years – and up to 166 years in the worst case.
Photovoltaic (PV) panels for power – and domestic, mast-mounted wind turbines – will take between 50 and 100 years to pay back.
Given that the devices have a maximum lifetime of 30 years, they are never likely to recoup the £3,000 to £20,000 cost of their installation, according to Rics’ building cost information service. Instead, it suggested people wanting to cut fuel bills should insulate lofts and cavity walls, install efficient light bulbs and seal windows.
During Colorado’s record-breaking cold of the last few days, I was able to find a few faggots of wood left in the pile, and keep the house warm.
I could have burned natural gas; but the price has been set too high, by Al Gore.
America is progressing back to wood-burning culture, and it’s not even really cold yet.
The snow-leopard’s terrain (Peter Matthiessen’s “The Snow Leopard”), treeless, is about to expand.
Good work, students of the environment.
As predicted here, aerosols with magical multiplicative properties, far superior to carbon dioxide, have now been found necessary to save AGW (Algoreogenic Global Warming).
Unfortunately, scientists cannot quite catch on to the complex concept that Earth is now COOLING.
Scientists are also having great difficulty with the link between low cloud formation and solar magnetic activity, since it is founded in stale history. As a result, we get this:
Can we blame lowly scientists for worshipping at the (cash, please) alter of Master Rainmaker Al Gore?
Yes; we surely can.
Richard Feynman comments colorfully on the Cargo Cult Science of Al Gore and James Hansen, far in advance (1974). As Luboš Motl relates it:
Feynman was trying to explain what’s wrong with various careless, agenda-driven, biased, preconceived mental frameworks that try to pretend that they are scientific but they don’t honestly eliminate falsified hypotheses according to the results of objective tests.
The falsified hypotheses of Al Gore and James Hansen are indeed resilient. On the surface, it’s not a scientific world, Richard; nor in the short term. We must admit to living in a world sullied by eruptions of cargo cult science, precisely as described in the video below. In the end, real science will inevitably triumph. Al Gore and James Hansen will sooner, or later eschew their cargo cult science, just as the aborigines of Australia have done.
