Wind-powered Cargo Vessel Holds Hope for a Greener Future

Ocean Conservancy

While a wind-powered cargo vessel may seem like a 19 th Century idea, the Grain de Sail may be a herald of a greener future rather than a nostalgic nod to the past. After agreeing to a very weak short-term measure in November 2020, the discussions last week focused on new measures that could take effect by 2030.

How Are Lithium-ion Batteries that Store Solar and Wind Power Made?

Union of Concerned Scientists

Batteries can also be used to assist with peak electricity demand; currently instead of batteries, fossil fuel-powered “peaker plants” are often used to supply energy during high-demand periods. Despite being used infrequently, these plants are inefficient and highly polluting, and contribute to US carbon emissions.

Climate Policy and the Audacity of Hope

Legal Planet

New California legislation will require corporations to disclose their carbon emissions. Wind power costs fell by half from 2008 to 2021. Rooftop solar costs in 2020 were a third of what they had been in 2010. In 2020, the cost of single-axis utility scale solar was only a fifth of what it was in 2010.

The EIA Just Released a 30 Year Energy Outlook. It’s… Not Great

Union of Concerned Scientists

CO 2 emissions remain mostly level through 2050—nowhere close to meeting US climate goals. Carbon emissions remain high. Wind capacity steadily increases, mostly due to policy (the federal tax credit, which expires in 2024, and state RPS policies).

How Will DTE’s Long-Term Plan Impact Michigan’s Clean Energy Future?

Union of Concerned Scientists

Earlier this year, the MPSC approved a settlement agreement on Consumers Energy’s integrated resource plan that commits the company to retire all its remaining coal-fired power plants by 2025, construct no new fossil gas infrastructure, and build large amounts of new solar power between now and 2040. What’s in DTE’s proposed plan?

Ask a Scientist: Two Dozen States Can Meet 100 Percent of Electricity Demand with Renewables by 2035

Union of Concerned Scientists

All told, they represent 56 percent of the US population, generate 62 percent of the country’s gross domestic product, and are responsible for 43 percent of the country’s annual carbon emissions. From 2020 to 2040, solar generation in these states jumps nearly ninefold and wind generation more than sevenfold.

What Happens If Glen Canyon Dam’s Power Shuts Off?

Circle of Blue

Kelly Sanders of the University of Southern California says the magnitude of a carbon emissions increase due to drought is difficult to calculate, owing to the complexity of electricity supply and demand. Customers of Glen Canyon power are confronting those tradeoffs as they search for replacement power.
