How much is climate warming (little if any), is it CO2’s fault (or solar output), what would it cost (alot) to get how much improvement (negligible), and would you trust global politics to manage it (since it’s a global problem)?
From today’s WSJ, Bjorn Lomborg in Climate-Change Misdirection
In the long run, the world needs to cut carbon dioxide because it causes global warming. But if the main effort to cut emissions is through subsidies for chic renewables like wind and solar power, virtually no good will be achieved—at very high cost…
Even in 2035, with the most optimistic scenario, the International Energy Agency estimates that just 2.4% of the world’s energy will come from wind and only 1% from solar. As is the case today, almost 80% will still come from fossil fuels. As long as green energy is more expensive than fossil fuels, growing consumer markets like those in China and India will continue to use them, despite what well-meaning but broke Westerners try to do.
Instead of pouring money into subsidies and direct production support of existing, inefficient green energy, President Obama should focus on dramatically ramping up investments into the research and development of green energy. Put another way, it is the difference between supporting an inexpensive researcher who will discover more efficient, future solar panels—and supporting a Solyndra at great expense to produce lots of inefficient, present-technology solar panels.
