Ray Kurzweil thinks we’re near a solar energy tipping point
A tipping point means that it’s more effective and less expensive than the alternatives, says Ray Kurzweil – inventor, writer, futurist, CEO of Kurzweil Technologies. He said he believes the tipping point for solar energy will come soon.
Solar power currently provides less than 1% of the world’s energy, but a panel of experts announced in early 2008 that solar energy is part of a sustainable future.
According to Kurzweil, solar energy is going to be economically attractive. ‘Even if particular organizations don’t care about the environment, they’re going to go with the least expensive solution. Solar energy has the added benefits that it’s renewable, it’s friendly to the environment, and we have plenty of solar energy. ‘We have 10,000 times more sunlight that we need to meet all of our energy needs,’ Kurzweil told EarthSky.
In energy, the tipping point is well defined – that is the cost per watt. Right now, using these old traditional solar panels, the energy per watt is 3 or 4 times more expensive than fossil fuels. But, solar energy cost is coming down, whereas fossil fuels are doing the opposite. And based on those trajectories, a crossing point where solar energy will be cheaper than fossil fuels is definitely within 5 years, maybe sooner, Kurzweil predicts.
