Voltage and Electricity

The radio program "Triangulation" from TWiT.tv explores the mysterious topic of electrical power in a conversation with Gretchen Bakke, author of "The Grid".

In the process she ended up discovering the nitty-gritty of how power generation works, the complexities of mixing renewable energy and batteries into the system, and having it all happen at the exact time when we need the energy to run our appliances.
