How Oregon Can Fill Up On Clean Fuels

Something big is brewing in Oregon. No, it’s not a new IPA from Portland-based Bridgeport Brewery—though that sounds delightful. It’s the next phase of Oregon’s Clean Fuel Program, a forward-thinking regulation that requires transportation fuel to get steadily cleaner on average, ultimately achieving a 10 percent reduction in carbon emissions per unit of fuel in 10 years. Extending this rule is a big deal because approximately one-third of Oregon’s greenhouse gases come from transportation, and Oregon has the in-state resource potential to produce significant amounts of clean fuels.

Electric Buses: How Plugs and Batteries are Replacing Wires and Diesel

Here’s how, and why we need more of them. Read More

Unfortunately, neither space nor climate change are receiving the attention they deserve from policy makers and the public. Fortunately, my 30-year career at NASA has given me the opportunity to become involved in both. Read More
