Tonopah NV solar plant generates power at night

The Crescent Dunes Concentrated Solar Power plant 200 miles northwest of Las Vegas in Tonopah is now coming online. Unlike photovoltaic, CSP solar plants can store energy and thus generate power at night. 10,347 tracking mirrors, each about the size of a billboard, reflect the sun’s heat to the Crescent Dunes central tower to heat […]

Electricity is expensive in Philippines, compounded by growing shortages. The government has responded by leasing more power, paying big customers to generate their own power (probably by diesel), yet these seem stopgap measures. With so many islands, distributed energy via rooftop solar could help substantially. The power profile of the three major island groups is […]

Off-grid homes as well as grid-connected homes with solar panels already have batteries to store energy. So really, why is this news, except that Tesla announced it with […]

Distributed generation increases electrical grid security

A few well-placed attacks could paralyze the existing US electrical grid, says former FERC Commissioner Jon Wellinghof. The best way to defend against such attacks, he says, is with distributed generation, not bigger walls and increased security. This is precisely where renewable energy, especially rooftop solar, can help. Wellinghoff believes the true answer to grid […]
