How would you like to never have another electric bill? Advances in technology have made it possible for some consumers to disconnect from the power grid — a move that was once only available to the ultra-wealthy who could afford the associated costs, or survivalists willing to trade convenience for freedom. This is no longer the case.

A recent study I coauthored with energy researcher Seyyed Ali Sadat reveals that the balance of economics has shifted and now many families may be better off financially by cutting ties to the grid. However, this might not be a good thing for everyone.

Back in the 2000s, solar was costly. The solar industry’s goal was to push the cost of solar panels below $3 per watt because that would produce solar electricity at a low enough cost to be economically competitive without subsidies. Over the year, the cost of solar plummeted.

By 2011, we showed for the first time in both the United States and Canada that the levelized cost of solar electricity had reached grid parity. This means people could have a net-metered, grid-connected solar system and pay the same for electricity as the grid costs.
