Let’s Talk Power Efficiency, Not Light Bulbs
Light bulbs sound like an innocent enough topic. And yet, during last week’s Congressional budget debate, light bulbs spawned a ferocious debate. One side claimed that the government was “coming for your light bulbs” while the other side fought to pour millions into phasing out incandescent bulbs in favor of their more energy-efficient counterparts. Both sides are wasting their breath because energy efficiency is only half the battle.
We have changed light bulbs, weatherized homes and turned down thermostats for the past decade with relatively little impact. We will not solve the challenges of an aging grid, rising electricity demand and a warming climate with energy efficiency. But we might just solve them with power efficiency.
Power efficiency is the next frontier in efficiency savings. It requires sophisticated software and predictive algorithms; but if done right, power efficiency holds the promise of using software instead of copper to keep up with rising electric demands on the grid. And we can do it for three to ten times less cost than current upgrades.
We’re currently paying hundreds of billions of dollars a year to update our grid with new hardware – bigger transformers, cables, and power gear. But this is where we err. The biggest challenge to our grid isn’t the amount of energy consumed (kWh), it is the peak electricity use during a given time period (kW).
Think of it this way: the grid has to be capable of handling the maximum demand. If a factory never ran all year except for one day when it did a highly electricity intensive process, we would still have to build the grid to accommodate that level of use. Extrapolate this idea across America and you have an electric grid that is built for a small number of high-use moments.
This is where the idea of power efficiency comes in. We can now use utility and weather data to predict demand and store energy accordingly. In doing so, we can significantly reduce stress on the electric grid and the amount of energy produced.
This isn’t just some pie-in-the-sky idea. All across America businesses and organizations are beginning to implement power efficiency technologies in order to cut costs. If these technologies were implemented across the entire United States, some estimate that we could save the energy equivalent of 4,000 coal plants per year.
We’ve changed a lot of light bulbs, now its time to start changing the whole system. Everyone wins when our society uses power more efficiently.
