The Clean Electric Economy

The Clean Electric Economy

Despite its promise, the electric transformation has barely begun, and much challenging work lies ahead. About 80 percent of today’s energy use comes to us not as electricity but by direct combustion of (mainly fossil) fuels. Only 20 percent of our energy is delivered through the electric grid and even this grid-energy is today more than two-thirds fossil-fueled. To reach our carbon targets and support new demands such as electric transportation, we must grow our grid-energy ratio to at least 50 percent by 2050, and 80 percent or more by 2100. We must also add clean power sources to lower the grid’s carbon intensity to about 20 percent by 2050. And, we must simultaneously upgrade our aging grid infrastructures, a measure long overdue on its own merits, independent of the need to meet climate goals.
