That is well above the base power load and the surge is supplied by less efficient fossil fuel power generators as well as some peak pumped water storage.
Home appliances, meters, transformers and generators could all share data and work together to make the power grid more efficient, for example by lowering the peak load.
Dull but highly tax-efficient and extremely low cost: This no-load index fund attempts to mimic the Wilshire 5000 by investing in large, mid and small caps.
