An associate of mine was testing out his off-road, off-grid solar power setup, and he came to some interesting […]

How many people think to fire up the Toyota Prius? For the last couple of months, in North America, the winter has been particularly brutal, with associated snowfall, ice, and power outages. Further north you go, […]

Renewable energy depends a lot on the weather. If the sun doesn’t shine, solar panels go dead. If the rain doesn’t fall, reservoirs behind hydroelectric dams go low and […]

Some electric vehicle makers and aftermarket companies have been producing vehicle-to-grid [V2G] technology, which enables an electric vehicle to serve as an emergency backup power source. In case of an […]
