OPINION: The Environmental Protection Agency recently announced new regulations governing tailpipe emissions for cars, SUVs and pickup trucks. The emissions cuts are so significant that automakers will be able to satisfy these rules only by selling more electric vehicles. By 2032, two-thirds of the new cars sold in the U.S. will be “zero-emissions vehicles” — that is, all-electric vehicles.

Russia’s invasion of Ukraine has boosted anxiety and therefore action on energy security and dependence on oil and gas. Sanctioning Russian oil and gas imports is an opportunity to replace fossil fuels with low or no carbon alternatives, an opportunity that is being taken. And renewables like wind and solar are by their nature local and therefore good for energy security (though with notable exceptions).

Key takeawaysDespite ambitious goals, renewable energies like offshore wind cannot fully replace the baseload power provided by fossil fuels due to inherent limitations in reliability and energy output. The economic viability of offshore wind projects is under scrutiny, with significant projects being abandoned due to insurmountable costs, rising interest rates, and regulatory challenges, highlighting the financial risks associated with transitioning to renewable energy sources.
