War in the Middle East is once again exposing the downsides of our addiction to oil and gas. Transportation and electricity costs are soaring for ordinary families, while multinational oil giants and Vladimir Putin reap windfalls. Then add in the usual planet-heating greenhouse gas emissions.

Understandably, $5-a-gallon gasoline and other fallouts from the energy crisis are inspiring calls for America to reduce its dependence on fossil fuels. And though it’s become unfashionable to say so, individual Americans can also change our expensive and destructive gas-guzzling ways. Yes, President Trump’s attacks on electric vehicles, renewable power and fuel-efficiency rules are awful. But nobody’s really stopping you from buying electric vehicles, installing solar panels or using less fuel.

It’s not a bad idea. You can save real money while doing a small part to help stabilize the climate, defund Big Oil and even reduce the risk of future conflicts in fossil-fueled nations like Iran and Venezuela. It’s true that your contribution to a better world will only be a drop in the bucket, but lots of individual drops, after all, are what fill buckets.
