Batteries could make power grid unnecessary in some countries

Aquion specializes in making large batteries, cheaply. They don’t look like much -- they live in a former TV factory outside Pittsburgh, and you'll probably never buy any of their products.

Why climate change is irrelevant to clean energy

Maggie Koerth-Baker, science editor at BoingBoing, has written a book. Here’s the basic idea: In America at least, if we want to get anything done on clean energy, we have to divorce it from conversations about climate change.

Myhrvold: 50 simple things won’t fix the climate — but a few complex things might

Nathan Myhrvold responds to follow-up questions about his paper that found that the transition to carbon-free energy must begin immediately.

Liquid battery electric vehicle could charge in three minutes

“Flow” batteries, i.e. batteries filled with a liquid electrolyte that can be pumped out and replenished, have the potential to transform the process of charging an electric vehicle into something that more closely resembles filling it up with gas.

Solar Power

Peel-off solar panels could make solar competitive with coal

Ultra-thin solar cells that can be "peeled off" from larger pieces of silicon like delicious fruit roll-ups could be the key to making solar competitive with coal, say researchers at MIT.

Renewable Energy

A battery large enough to power the U.S. would be the size of 2,200 Walmart SuperCenters

Renewables are intermittent, so they'd have to be backed up by about 80 gigawatts worth of batteries.

DOE-funded battery breakthrough to halve cost, triple range

A new breakthrough from California-based Envia Systems will yield lithium-ion batteries that are less than half the cost of current cells, while also having three times the energy density.

LEGO buys $500 million worth of wind turbines

The world's third-largest toy manufacturer is going to be putting "made with wind power" labels on all those boxes of LEGOs, and not just because they bought their power from utilities with wind turbines.
