Electric Heat: A Barrier to Renewable Energy

Electric Heat: A Barrier to Renewable Energy

This PV array will not keep you warm.   Electric Heat: A Barrier to Renewable Energy Renewable energy technologies, when integrated within an offgrid diesel-powered microgrid, can reduce pollution and, when done well, generation costs. However, the first, essential step is often neglected: reducing the community's demand for electricity. This post will focus on the main challenge: electric heat. Electric heat: a pollution multiplier In remote communities, electricity is often used for space heating, water heating, cooking and lighting. The lion's share of electricity use comes from electric heat (baseboard or furnaces) and water heaters, with the highest demand occurring in winter. Electric heat systems are cheap to install and convenient. However, diesel generators are at best 30% efficient, meaning that only 30% of the energy of diesel combusted becomes…
