    we don't have to do it with solar alone. It's great that we can! With the combination of all renewables, solar, wind, water (hydro), geothermal where appropriate all deployed at the most optimal locations for each, can theoretically drop the demand for fossil fuels even sooner, IF THERE WAS THE WILL to do so. It is one of my biggest wishes.

    Truth is harmonious, lies are discordant.

    •  And there is still a huge upside for conservation (10+ / 0-)

      public transport, house insulation, LED light bulbs, etc. etc. all save a lot of energy, often with an improvement in the quality of life.

        I recently replaced a 40 watt incandescent that was on most nights for around 5-6 hours with a 7 watt CFL. I'd have done this sooner but it's in a lamp with one of those mini chandelier sockets and it was hard to find a cheap CFL to go in it. Home Depot has them on sale for under $6 for 3, subsidized by LIPA.

        I mostly walk or ride my bike to get places, over 20 years with the same car and it's barely cracked 75k. It's not THAT hard to conserve.

        •  I replaced 25 watt bathroom mirror lights with LED (2+ / 0-)

          lights I got for seven dollars. The LEDs use less than 2 watts AND put out no real heat. I did it without telling anyone and waited to see if anyone noticed the difference. After they didn't I told them and at first they didn't believe me. I had to have them touch the plastic globes and notice they were not at all hot to prove they were LEDs and use about a tenth of the power of the old bulbs. Plus with very little heat it saves on air conditioning and the new bulbs expected life is about twenty three years not one or seven.

          I also replaced a 7 watt night light with an LED that is less than 1 watt.

          Now if they could figure out how to make air conditioners that are as frugal.

      •  Yes, it improves the quality of life for sure! (1+ / 0-)

        We insulated, put in LEDs in our most used outlets, and we are warmer, cooler and use less electricity so it costs us less.
