A new report shows the “unacknowledged tax” of the Iran energy price shock.

“This data shows that energy price shocks function as an economy-wide, unacknowledged tax on households, with costs comparable to large federal programs and policies,” said the Climate Solutions Lab director.

Energy costs have been walloping the working class since the United States and Israel attacked Iran on Feb. 28. And things could get a lot worse this summer, with prices rising ever higher the longer the Strait of Hormuz remains closed to shipping.

On the day our oil-stained president returned to the White House, he began an all-out assault on clean energy. Today, 16 months later, he and his party are paying a significant political price while American consumers are stuck with the bill.

Brown University professor Jeff Colgan and his team at the Climate Solutions Lab have found that increasing gas price costs across the country have added up.

Successfully blocking Iran’s ports will drive up global energy prices even more.

Jeff Colgan comments for CBS News, "Whether it's from Amazon or from a grocery store, everything gets touched by diesel prices because diesel is the fuel by which all of the goods in our economy really get shipped around."

"You're probably feeling it in ways you don't realize.”

“It’s coming right out of your pocket.”

The 704-megawatt offshore wind farm comes amid rising oil and gas costs tied to the ongoing war in Iran.

The US-Israeli offensive against Iran has entered its third week. With crude oil prices continuing to soar, will the global economy face a repeat of the oil crisis (oil shock) that shook the world in the 1970s and 80s? Jeff Colgan, a professor of political economy at Brown University and an expert in the energy sector, points out that "this is an energy crisis different from what the Middle East has experienced in the last 50 to 60 years."

The framework proposes long-term solutions over short-term mitigation efforts.

Since the start of the 20th century, oil has been the life blood of global development. And both the US and Venezuela have played a critical role in the history of that oil flow.

Two experts discuss how the U.S. and the world move forward with climate mitigation.

Since Jan. 20, 2025, the first day of his second term in office, President Donald Trump has slashed U.S. foreign aid spending. Amid continued budget cuts, international NGOs have adopted several strategies to keep operating and meeting their missions.

Jeff Colgan, a professor at Brown University, says the US has resumed a "bullying" approach to international relations in order to gain economic advantages.

Even as the world warms, oil attracts conflict. Just look to Venezuela and Donald Trump’s moves to control the country’s vast reserves. We delve into the history of "petro-imperialism” and ask whether a planet powered by renewables would be any more peaceful.

The country’s “extra heavy” oil packs some of the highest associated greenhouse gas emissions of any crude oil.

To understand what just happened in Venezuela, look at oil politics and U.S. foreign policy.

Ten years ago, negotiations concluded on the first truly global climate treaty, the landmark Paris Agreement. Why has this major diplomatic achievement had only limited success in reaching its goals?
