Renewable energy boom will mean vastly cheaper electricity

Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity — and solar power that’s less expensive than what fossil fuel-based power plants can produce.

Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion, according to Tesla CTO JB Straubel.

What Are The Roadblocks To More Renewables? — Bob Stojanovic and Dennis McKinley | CleanTechnica

Posted by in category: energy

“We have the technology to successfully integrate distributed, renewable energy with the grid to provide a reliable, seamless power source. That includes software that helps renewable-power providers better predict their output throughout the day and feed that information upstream to utilities so they can blend that power with their traditional generation portfolio…The real barrier to greater renewable use is less technological and more philosophical. People worry that connecting all these renewable sources to the grid will bring it down.” Read more

2015-7-EVGuide-illo-WB

I’M driving 550 miles in three days, all by myself, mainly for the fun of it—and I’m not an environmental villain. Behind the wheel of a borrowed bright-red electric Tesla Model S, I click off the miles as I head south from the San Francisco Bay Area on Interstate 5 through California’s San Joaquin Valley, feeling virtuous because my tailpipe spews no pollution.

‪#‎Handy‬ New Wireless Charger Can Simultaneously Power 30 Mobile Phones at Distance.

Scientists at the Korea Advanced Institute of Science and Technology (KAIST) have developed an omnidirectional wireless charging technology that can charge multiple devices at once, at a distance and, crucially, at peak efficiency regardless of which way the devices are facing.

An effective wireless transmitting power of 30 watts means the device can, according to the researchers, power either 30 smartphones or five laptops simultaneously.
