How smart is a smart grid?

A smart grid is a complex computerized management system designed to distribute the power available to the grid in an efficient manner relative to demand while maintaining grid stability. It does not generate any new power except in so far as it saves some energy that would be wasted with a less efficient system. Because of limited storage capacity a smart grid is also capable of maximizing energy use over only short periods; it will not solve the intermittency problem over longer periods. It is also likely to be costly. There are also questions as to whether current designs based on computer simulations will work in practice. Continue reading

Blowout Week 118

This week we focus on solar power in the United States. A report by the US National Renewable Energy Laboratory has concluded that the country can fill 39% of its electricity needs with rooftop solar PV alone. And that doesn’t include the “immense potential” of ground-mounted PV units. Is an all-solar America on the horizon? Continue reading
