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. Emissions of sulfur dioxide and nitrogen oxides from power plants in alliance states drop 88 percent and 77 percent respectively by 2040.

Hydrogen and “Renewable” Gas Aren’t Realistic Solutions for Decarbonizing Maine’s Buildings

Union of Concerned Scientists

Included in that original bill was an ending of subsidies for expansions of gas distribution systems within the state—an important and significant step in stopping the growth of carbon dioxide and methane emissions from the state’s buildings sector. The fuel still emits carbon dioxide (CO 2 ) when burned.

Unraveling LA’s Hydrogen Combustion Experiment

Legal Planet

This is partly because hydrogen production is energy inefficient and––when derived from fossil fuels––still a significant source of carbon emissions. By combusting hydrogen, these natural gas plants would stay online, but they would have a somewhat smaller carbon footprint, and could provide firm energy to meet demand.

Five Reasons “Natural” Gas is Bad for You and the Environment

Enviromental Defense

Fossil gas is mostly made up of a greenhouse gas called methane which is more potent than carbon dioxide and is responsible for about 30 per cent of the rise in global temperatures. Fossil gas is bad for our health Gas plants emit nitrogen oxides which increase smog and can cause respiratory problems for people living nearby.

Killing King Coal is the First Step Towards Halving Our Emissions

Edouard Stenger

As I have spent some sleepless nights since the latest IPCC report on how Mankind has to halve its carbon emissions by 2030. As we shall see, this is already currently happening, it is the moral thing to do, the best economic choice, and the fastest and easiest way to halve our emissions. A moral imperative.

The IRA and Net Zero scenarios also drive significant reductions in nitrogen oxides (NOx), sulfur dioxide (SO2), and fine particulate matter (PM2.5). carbon capture and storage and carbon dioxide removal, which show up in a bounded way in our model results).

Ask a Scientist: Top Takeaways from the New EPA Carbon Pollution Rules

Union of Concerned Scientists

Last month, the Environmental Protection Agency (EPA) proposed new power plant carbon pollution standards that, if strengthened, would go a long way to help meet the Biden administration’s goal of slashing carbon emissions in half from 2005 levels by the end of this decade. EN: First, why are these new standards such a big deal?
