Ecosummit TV: Steven Fawkes of Day One Energy Solutions talks about the magic of energy efficiency at ECO13 Berlin. How (in)efficient are we? The answer is 11%. Out of 475 exajoules primary energy like fossil fuels or renewables, we only get 55 exajoules useful energy like heat or electricity. That’s why Steve’s blog is called Only Eleven Percent. So there is a massive potential for improvement. In fact, the levelized cost of energy (LCOE), which is a combination of capital costs, operations and maintenance, performance and fuel costs, of energy efficiency is the lowest compared to all other sources of energy. In his talk, Steve gives a couple of examples where investments in energy efficiency will generate fast returns.

The ECO13 Berlin presentation slides of Steven are available as PDF.
