Michigan Tech Study Shows Ditching Coal for Solar Saves Lives — AND Money

HOUGHTON — In a new study published in the academic journal Renewable & Sustainable Energy Reviews (DOI: 10.1016/j.rser.2017.05.119), a team from Michigan Technological University calculated the cost of combusting coal in terms of human lives along with the potential benefits of switching to solar.

Health Impacts

Tens of thousands of Americans die prematurely each year from air pollution-related diseases associated with burning coal. By transitioning to solar photovoltaics in the United States, the study found up to 51,999 American lives would be saved at $1.1 million invested per life.

“Unlike other public health investments, you get more than lives saved,” said Joshua Pearce, a professor of materials science and electrical engineering at Michigan Tech. “In addition to saving lives, solar is producing electricity, which has economic value.”

Using a sensitivity analysis on the value of electricity, which examines the different costs of electricity that varies by region throughout the country, saving a life by using solar power also showed potential to make money — sometimes as much as several million dollars per life, says Pearce.

“Everybody wants to avoid wasting money. Just based off the pure value of electricity of the sensitivities we looked at, it’s profitable to save American lives by eliminating coal with solar,” he explains.

Pearce worked with energy policy doctoral student Emily Prehoda on the study, and their main goal was to better inform health policy. They gathered data from peer-reviewed journals and the Environmental Protection Agency to calculate U.S. deaths per kilowatt hour per year for both coal and solar. Then they used current costs of solar installations from the Department of Energy and calculated the potential return on investment.

Pearce and Prehoda also analyzed the geographic impact of coal-related deaths. “Here, we have solid numbers on how many people die from air pollution and what fraction of that is due to coal-powered plants in each state.”

Power of Solar

To fully replace all the coal production in the U.S. with solar PV, it would take 755 gigawatts — a significant increase compared to the 22.7 gigawatts of solar installed in the U.S. currently. The total cost of installing that much solar power totals $1.5 trillion, but that investment is figured into Pearce and Prehoda’s calculations, and is a profitable investment.

Said Pearce: “Solar has come down radically in cost, it’s technically viable, and coupled with natural gas plants, other renewables and storage, we have ways to produce all the electricity we need without coal, period.”

He says resisting the rise of solar energy is akin to if computer manufacturers kept using vacuum tube switches instead of upgrading to semiconductor transistors.

“My overall take away from this study is that if we’re rational and we care about American lives, or even just money, then it’s time to end coal in the U.S.,” Pearce said.

Next Steps

The World Health Organization reports that millions die each year from unhealthy environment, air pollution notably the largest contributor to non-communicable diseases like stroke, cancers, chronic respiratory illnesses and heart disease. Future work can expand this study globally.

“There’s roughly seven million people who die globally from air pollution every year, so getting rid of coal could take a big chunk out of that number as well,” Pearce said, adding that another goal of future research is to dig deeper into the life cycles of coal production as this study only looked at air pollution related deaths. Doing so will continue to illuminate the multiple positive impacts of solar power and its potential to do more than keep the lights on.

Michigan Tech Research: Solar Can Aid Military Security Affordably

HOUGHTON — Vulnerabilities in the power grid are one of the most prevalent national security threats. The technical community has called for building up the resiliency of the grid using distributed energy and microgrids for stabilization. Power production from multiple sources increases the difficulty of triggering cascading blackouts, and following an attack or natural disaster, microgrids can provide localized energy security.

In a new paper published in the academic journal Renewable and Sustainable Energy Reviews (DOI: 10.1016/j.rser.2017.04.094), an interdisciplinary team of engineering and energy policy experts from Michigan Technological University says the first step is to outfit military infrastructure with solar photovoltaic-powered microgrid systems. Their results found that the military needs 17 gigawatts of PV to fortify domestic bases — and that the systems are technically feasible, within current contractors’ skill sets, and economically favorable.

Additionally, the paper’s lead author, Emily Prehoda, who is finishing her PhD in energy policy at Michigan Tech, says boosting bases’ energy independence supports local communities.

Solar energy jobs in Michigan jump 48% in 2016

LANSING – The Michigan Energy Innovation Business Council, a trade association for renewable energy companies, announced Monday that a new report from the Solar Foundation found that jobs in Michigan’s solar industry jumped by an impressive 48 percent from 2015 to 2016.

During that time, Michigan solar companies added more than 1,300 jobs, for a total Michigan solar workforce of 4,118.

This positions Michigan second in the Midwest both in terms of growth rate and number of individuals employed in the solar industry, Nationally, Michigan now ranks 15th in the number of solar jobs, up three spots since 2015. (Ohio leads the Great Lakes are with 5,831 solar jobs, and employment grew there 21 percent in 2016. Indiana had the fastest growth rate, 72 percent, but has the smallest number of solar jobs in the region, 2,700.)

Nationally, the Solar Jobs Census 2016 reported that solar employment has nearly tripled since 2010 and was up 25 percent over 2015, with the industry adding more than 21,000 jobs in 2015 for a total of more than 260,000 solar workers nationally. This is the fourth consecutive year of more than 20 percent national solar job growth. Last year, one out of every 50 jobs created in the United States was in the solar industry. Notably, solar now employs twice as many people as the entire U.S. coal industry, and the same number as work in natural gas.

The Michigan EIBC represents companies across the full range of the advanced energy sector, including advanced materials, biomass and biofuels, energy efficiency, energy storage, lighting, smart grid, solar, transportation, and wind.

Plug In For Renewable Energy

HOUGHTON — Support for solar energy is vast. According to a 2015 Gallup poll, 79 percent of Americans want the US to put more emphasis on developing solar power. Most of the same people, unfortunately, can’t afford to install solar energy systems in their homes. Even after federal tax credits, installing solar panels to cover all of a family’s electricity needs can cost tens of thousands of dollars. For others, a home solar system isn’t a consideration because they rent, or move frequently.

But Michigan Technological University’s Joshua Pearce says he knows the solution: plug and play solar.

“Plug and play systems are affordable, easy to install, and portable,” said Pearce, an associate professor of materials science and engineering and of electrical and computer engineering. “The average American consumer can buy and install them with no training.”

In a study funded by the Conway Fellowship and published in Renewable Energy (DOI: 10.1016/j.renene.2016.11.034), Pearce and researchers Aishwarya Mundada and Emily Prehoda estimate that plug and play solar could provide 57 gigawatts of renewable energy – enough to power the cities of New York and Detroit – with potentially $14.3 to $71.7 billion in sales for retailers and $13 billion a year in cost savings for energy users.

Sounds great, right? Well, there’s one problem: in many parts of the United States, electrical regulations don’t allow consumers to plug and play.

Small investment, big return

Plug and play solar panels connect to an ordinary electrical outlet. You’re still on the grid, but you’ve become a “prosumer” — a consumer of energy who also produces it. The panels range in wattage and are relatively affordable, with some costing just a couple of hundred dollars. A prosumer can start small, with just one panel, and slowly build up over time to a system that produces 1 kilowatt of energy, the equivalent of powering 10 100-watt light bulbs.

The panels are also portable. So, for example, if a college student buys one 250-watt plug and play panel each year for four years, reaching 1 kilowatt of energy by senior year, that student can unplug the four panels when she graduates and take them to her next destination.

Pearce estimated that plug and play systems could generate more than four times the amount of electricity generated from all of U.S. solar last year.

“The vast majority of this energy never leaves the home,” Pearce said. “It’s the equivalent of handling a hair dryer load. We’re talking about almost nothing on the electrical grid – but that nothing adds up. It’s an appliance with a high rate of return.”

Safe, simple — and largely prohibited

In the U.S., a patchwork of local jurisdictions and regulations make it difficult to figure out if and where plug and play panels are allowed.

“You can buy the panels, but you might not be able to plug them in, depending on your utility,” Pearce said.

In a paper published earlier this year in Solar Energy (DOI: 10.1016/j.solener.2016.06.002), Pearce, Mundada and researcher Yuenyong Nilsiam reviewed all regulations in the U.S. that would apply to plug and play systems. They found no safety or technical issues with the equipment on the market.

“This is an area where less regulation could really help renewable energy,” Pearce said. “We know that the technology is safe, and the law should reflect that.”

The risk, according to Pearce, is putting too much current on one circuit, so he recommends that homeowners keep their plug and play systems to a kilowatt or less. Simple precautions make this easy — if a panel is plugged into an outdoor outlet, for example, safety plugs on all other outdoor outlets on that circuit can prevent overload.

While some jurisdictions have recognized that there are no major safety or technical issues with plug and play panels, paperwork holds up the process. Potential prosumers often have to fill out complicated forms to fulfill utility requirements, and the paperwork and associated fees vary by utility. To simplify the process, Pearce and colleagues automated it, by writing open-source computer code that fills out every possible technical requirement. Utilities can easily use the free code on their websites.

“Some utilities have embraced plug and play, and some have ignored it because they think it’s a pittance,” Pearce says. “But plug and play solar is something that can help most Americans.”
