We Can Stop Searching For The Clean Energy Miracle. It's Already Here. Key climate solutions have been advancing considerably faster than anyone expected just a few years ago thanks to aggressive market-based deployment efforts around the globe.
These solutions include such core enabling technologies for a low-carbon world as solar, wind, efficiency, electric cars, and battery storage. That’s a key reason almost everything you know about climate change solutions is probably outdated. In Part 1 of this series, I discussed other reasons. For instance, climate science and climate politics have moved unexpectedly quickly toward a broad understanding that we need to keep total human-caused global warming as far as possible below 2°C (3.6°F) — and ideally to no more than 1.5°C. But the media and commentariat generally have not kept up with the science or solutions and their utterly game-changing implications.
The world can be powered by alternative energy, using today's technology, in 20-40 years, says Stanford researcher Mark Z. Jacobson. January 26, 2011 A new study – co-authored by Stanford researcher Mark Z.
Jacobson and UC-Davis researcher Mark A. Delucchi – analyzing what is needed to convert the world's energy supplies to clean and sustainable sources says that it can be done with today's technology at costs roughly comparable to conventional energy. But converting will be a massive undertaking on the scale of the moon landings. What is needed most is the societal and political will to make it happen. 'If I burn out, I burn out': meet Taylor Wilson, nuclear boy genius. Taylor Wilson has a Geiger counter watch on his wrist, a sleek, sporty-looking thing that sounds an alert in response to radiation.
As we enter his parents’ garage and approach his precious jumble of electrical equipment, it emits an ominous beep. Wilson is in full flow, explaining the old-fashioned control panel in the corner, and ignores it. “This is one of the original atom smashers,” he says with pride. “It would accelerate particles up to, um, 2.5m volts – so kind of up there, for early nuclear physics work.” New paper shows that renewables can supply 100% of all energy (not just electricity) Posted on 20 August 2015 by michael sweet A new paper: 100% clean and renewable wind, water, and sunlight (WWS) all-sector energy roadmaps for the 50 United States by Jacobson et al 2015 describes the wind, solar and other renewable technologies needed to supply all the energy used in the USA That is all the energy, not just the electricity.
They find that using wind to generate 50% of energy, solar photovoltaic (PV) for 38%, concentrated solar power (CSP) for 13% and a combination of hydro, geothermal, tide and wave power for the remainder (5%) allows all energy in the USA to be supplied at a lower cost than using fossil fuels. (The total is over 100% as extra power is required to stabilize the power grid because the wind does not always blow and the sun does not always shine). The jobs required to build and run the renewable power supply would be greater than the jobs lost by closing down the fossil and nuclear power suppliers.

Technology As the population continues to grow, and fossil fuels continue to dwindle, we’ll find it increasingly hard to produce energy, food, and clean water.
But advances in technology—some simple, some mind-boggling—are unveiling new ways for us to thrive on the planet’s limited resources. Ward's Cheap Power System. We've been asked the same question over and over, ever since Otherpower.com was created: 'How cheaply can I build a solar power system?
' The answer, of course, is 'it depends on what you want to run! ' If you want to run a normal house in town off of solar, you're in for a investment of tens of thousands of dollars, thanks to a house that's almost certainly full of power-wasting, inefficient lights and appliances. But if you can start from scratch...that's a different story! The awesome little 7-sided log cabin Ward bought has never had an electrical system...in fact it was built back the 1960s using NO POWER TOOLS of any kind. The builder didn't believe in power tools...It's located only a mile from Otherpower.com headquarters.
