Shift to renewable electricity a win-win at statewide level

Amid rollbacks of the Clean Power Plan and other environmental regulations at the federal level, several U.S. states, cities, and towns have resolved to take matters into their own hands and implement policies to promote renewable energy and reduce greenhouse gas emissions. One popular approach, now in effect in 29 states and the District of Columbia, is to set renewable portfolio standards (RPS), which require electricity suppliers to source a designated percentage of electricity from available renewable-power generating technologies.

Boosting levels of renewable electric power not only helps mitigate global climate change, but also reduces local air pollution. Quantifying the extent to which this approach improves could help legislators better assess the pros and cons of implementing policies such as RPS. Toward that end, a research team at MIT has developed a new modeling framework that combines economic and air-pollution models to assess the projected subnational impacts of RPS and carbon pricing on air quality and , as well as on the economy and on climate change. In a study focused on the U.S. Rust Belt, their assessment showed that the associated with air quality improvements from these policies would more than pay for the cost of implementing them. The results appear in the journal Environmental Research Letters.

"This research helps us better understand how clean-energy policies now under consideration at the subnational level might impact local air quality and ," says the study's lead author Emil Dimanchev, a senior research associate at MIT's Center for Energy and Environmental Policy Research, former research assistant at the MIT Joint Program on the Science and Policy of Global Change, and a 2018 graduate of the MIT Technology and Policy Program.

Burning fossil fuels for energy generation results in air pollution in the form of fine particulate matter (PM2.5). Exposure to PM2.5 can lead to that include lung cancer, stroke, and heart attacks. But avoiding those effects—and the medical bills, lost income, and reduced productivity that comes with them—through the adoption of cleaner energy sources translates into significant cost savings, known as health co-benefits.

Applying their modeling framework, the MIT researchers estimated that existing RPS in the nation's Rust Belt region generate a health co-benefit of $94 per ton of carbon dioxide (CO2) reduced in 2030, or 8 cents for each kilowatt hour (kWh) of deployed in 2015 dollars. Their central estimate is 34 percent larger than total policy costs. The team also determined that carbon pricing delivers a health co-benefit of $211 per ton of CO2 reduced in 2030, 63 percent greater than the health co-benefit of reducing the same amount of CO2 through an RPS approach.

In an extension to their published work focused on the state of Ohio, the researchers evaluated the health effects and economy-wide costs of Ohio's RPS using economic and atmospheric chemistry modeling. According to their best estimates, an average of 50 premature deaths per year will be avoided as a result of Ohio's RPS in 2030. This translates to an economic benefit of $470 million per year, or 3 cents per kWh of renewable generation supported by the RPS. With costs of the RPS estimated at $300, that translates to an annual net health benefit of $170 million in 2030.

When the Ohio state legislature took up Ohio House Bill No. 6, which proposed to repeal the state's RPS, Dimanchev shared these results on the Senate floor.

"According to our calculations, the magnitude of the air quality benefits resulting from Ohio's RPS is substantial and exceeds its economic costs," he argued. "While the state legislature ultimately weakened the RPS, our research concludes that this will worsen the health of Ohio residents."

The MIT research team's results for the Rust Belt are consistent with previous studies, which found that the health co-benefits of climate policy (including RPS and other instruments) tend to exceed costs.

"This work shows that there are real, immediate benefits to people's health in states that take the lead on clean energy," says MIT Associate Professor Noelle Selin, who led the study and holds a joint appointment in the Department of Earth, Atmospheric and Planetary Sciences and Institute for Data, Systems and Society. "Policymakers should take these impacts into account as they consider modifying these standards."

So, in china..they have developed the ability to switch to solar power, through the creation of so many solar panel production plants and cost reductions .. It is now feasible in china, to make most major areas be solar power based, etc at BELOW all possible considerations for their grid costs.

To become immune to oil power.

Meanwhile, the global hegemony asshats of the west, are committed to every underhanded, sociopath nutbar war mongering technique possible...to force the west to pay for their global domination scheme, by corrupting any governmental motion or corporate motion toward saving the planet by moving to solar and other renewable energy production and use systems.

Figure it out people...-the visible government has no say or sway in this.

Think Epstein.. and the claims he was an 'intelligence asset', for blackmail and control.

The reality is far deeper and far worse than Epstein.

When you can't find causal aspects, then they must be where you're not looking.

I have a wonderful testimony to share to the whole world on how Papa Egbe used his herbal product on me, I have been affected with HSV for 6 years and I might papa Egbe through a testimony shared by someone online and told my self let me give him a try and visiting many hospitals and herb home for cure and so lucky for me he did a wonderful job on me and the virus I have had for 6 years was completely cured, thank to Papa Egbe for making me healthy again.

It doesn't quite work that way.

For example, in Beijing, the average number of sunlight hours per year is 2707 out of 8760 total hours, so no matter how much solar power you build, you will only have (some) power 31% of the time.

That's 7 hours 20 minutes per average day, and the rest of the time the Chinese would still mostly burn coal.

a) Half-a-degree warmer means 30,000 more deaths.

Or

b) This translates to an economic benefit of $470 million per year, or 3 cents per kWh.

Choose a or b. The choice is obvious, isn't it climate change denier goon squad.

Another steaming load of unsubstantiated AGW Cult bullshit.

yeah, fascist quislings like shoofly & auntie & raddled boy & hacksd hate even the suggestion of people taking responsibility for their lives & the future of this world
with conservative actions to improve efficiency through community development of local power sources
with a partnership of public & privately owned distribution

instead the politically correct. ideologically pure wethers bleating altright slogans & denier propaganda on behalf of the global axis of the russians & saudis
