Ask a Scientist: The US Has to Do More to Meet Its Carbon Emissions Reduction Goals

Union of Concerned Scientists

However, several analyses—including a recent one by the Union of Concerned Scientists (UCS)—have concluded that the IRA, even when coupled with the bipartisan infrastructure act and other federal and state climate policies, will not be enough to meet US carbon emission reduction goals. Energy efficiency also plays a critical role.

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.

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.

Building a Better Power Grid for Minnesota

Union of Concerned Scientists

Minnesotans are facing concurrent crises of climate change, high energy prices and inflation, and the inequitable public health impacts of fossil fuel air pollution. Renewable energy will help with all of that—but we need a grid that is designed for wind and solar instead of having to rely on expensive coal and gas plants.

Boosting Michigan’s Energy Future with Regional Transmission Upgrades

Union of Concerned Scientists

This much-needed set of 18 projects will improve electricity reliability, address overloaded wires , and help unlock more lower-cost wind and solar power to replace costly, polluting fossil fuel plants in Michigan and many other states in the Midwest (including Illinois and Minnesota ).

EU’s carbon price surging towards an all-time high

A Greener Life

Forecasts of cool weather and expectations of lower wind power output had driven up demand for more fossil-fuel produced energy. The EU’s emissions trading system forces manufacturers, power companies and airlines, to pay for each tonne of CO2 they emit, in an effort to reduce emissions and to meet climate targets.

Unraveling LA’s Hydrogen Combustion Experiment

Legal Planet

Hydrogen’s supply-side has been buttressed by incentives from state and federal governments, refineries and utilities looking to extend the life of fossil fuel infrastructure, and renewable energy companies seeking to take advantage of the huge amounts of clean energy needed to produce green hydrogen.
