Renewable Energy Hub

Nanoscience is quite fascinated with the process of photosynthesis. They want to duplicate this process exhibited by green plants and utilize the solar power for energy use. Till now power generating solar panels are not in a position to replace the fossil fuels. They produce little amount of energy and quite expensive also. Generation [...]

It’s a one-two green punch for the trucking industry: today the Port Authority of New York and New Jersey announced a program with the U.S. EPA to help get rid of older trucks with dirty emissions, and just yesterday the company New Energy Technologies announced another step forward for device that can harvest sustainable kinetic energy from trucks as they, well, keep truckin’ on.

If you ever grew up on an urban truck route (which I did), the idea of green trucks might seem like an oxymoron but hey if the trucking industry can get their sustainability act together then by golly you betcha just about any major commercial sector can (except for maybe this one).

Here’s one electricity storage technology that’s been around for over 20 years, under the radar, but might be due for a resurgence in interest with the addition of more wind power to the grid.  Wind tends to blow at night when we don’t need it.

Steffes Electric Thermal Storage makes devices that store excess off-peak renewable electricity very simply, as heat, by heating up electric coils surrounded by ceramic bricks in a sealed container. The ceramic bricks are thermal sinks. They soak up the heat slowly, and when triggered to, can release that heat, just as slowly, providing low-cost heating.

Excess electricity generated can be stored at any time, like at night from excess wind power, and then released at any time it’s needed; on demand, in the form of heat.

Because it is useful for businesses and homeowners, it is distributed energy storage.

Sunpods Inc. is California-based manufacturing company. They produce modular, fully integrated and tested solar power generation systems. Recently they have come out with an idea of the first solar power-assist system for buses. They should be applauded for developing it in a mere six weeks. Their partner is Bauer Intelligent Transportation. The system developed [...]

“It’s not too late; we can minimize the alteration, or we can just plow on as usual … and if we plow on as usual … it could be very, very bad.” So says Nobel Prizewinner for Physics, Steven Chu, who is now Energy Secretary of the Obama administration Department of Energy – at Stanford University this week.

“Speaking to the choir” (peer reviewed scientists and the educated already understand the problem) but really addressing the Senate Republicans who need to pass climate legislation, Chu stressed the danger and risks of inaction.

Much of the outcome will depend on the Earth’s response to an anticipated temperature increase of five or six degrees centigrade, an effect that won’t take hold for another 100 to 150 years, he said.

That’s when the oceans, a vast storage sink for carbon dioxide released into the atmosphere, are expected to reach capacity and begin expelling gases back into the air.

There are great uncertainties as to the outcome awaiting us if we continue business as usual by relying on a fossil-fuel-guzzling energy infrastructure to meet everyday needs, said Chu.
