Editorial: Environmental sirens are sounding

If things don’t change soon, we’re toast. We saw it last week when Hurricane Michael wiped out entire communities in Florida and last month when Florence wreaked havoc in the Carolinas. We’ve seen it on Long Island, where we will face even worse flooding than the destruction from superstorm Sandy. The Earth is getting hotter, and more-intense storms are only one result. If we don’t stop the warming, the changes will be...

States can lead the way on climate change policy a...

As Trump guts environmental protections, states must take charge on smart climate policy. The world’s leading panel of climate experts sounded the alarm this week that we are running out of time to get rising temperatures under control. Its latest report calls for “rapid, far-reaching and unprecedented” steps to avoid the worst impacts of climate change, from worsening wildfires and extreme drought to rising sea levels and...

Editorial: The government needs to take action aga...

On Oct. 8, the U.N. Intergovernmental Panel on Climate Change released a report saying humanity has until 2030 to prevent a disastrous level of global warming. If we continue on the same path, by 2030 the Earth will have warmed by 1.5 degrees Celsius. This may not seem like a lot, but a temperature increase of this magnitude would drastically increase “climate-related risks to health, livelihoods, food security, water...

Climate reality requires starting at home: Weaning...

Fossil fuels have to go. It didn’t take the latest report from the International Panel on Climate Change (IPCC) to tell us that: we’ve known it for three decades. But the report makes it clearer than ever: Burning billions of tons of coal, oil, and natural gas is creating a thickening blanket over the Earth, holding in its heat and disrupting all kinds of systems, from oceans temperatures and chemistry to storm patterns,...

Net-zero emissions energy systems

Prof. Nathan S. Lewis from California Institute of Technology mentioned this article during his presentation at Denison on 10/11/2018. Path to zero carbon emissions Models show that to avert dangerous levels of climate change, global carbon dioxide emissions must fall to zero later this century. Most of these emissions arise from energy use. Davis et al. review what it would take to achieve decarbonization of the energy...

Why We Can’t Reverse Climate Change With ‘Negative...

In a much-anticipated report, the Intergovernmental Panel on Climate Change (IPCC) said the world will need to take dramatic and drastic steps to avoid the catastrophic effects of climate change. Featured prominently in the report is a discussion of a range of techniques for removing carbon dioxide from the air, called Carbon Dioxide Removal (CDR) technologies or negative emissions technologies (NETs). The IPCC said the...

Climate Change Economists Win Nobel Prize

The Royal Swedish Academy of Sciences announced the 2018 Nobel Prize in Economics to a duo for their work on how the world can achieve sustainable growth. The prize was divided equally to William D. Nordhaus of Yale University and to Paul M. Romer of New York University’s Stern School of Business, both Americans, who have “designed methods for addressing some of our time’s most basic and pressing questions...

Historical records in the climate crosshairs

Climate change is a high priority for many Americans. But on election days, many of those passionate environmentalists do not vote. Stinnett: “We’ve identified 10.1 million who didn’t even vote in the 2016 presidential election, an election that was only decided by seventy-seven-thousand votes. So this is an enormous population of environmentalists just waiting to be energized.” They contact unlikely voters – Republican,...

Homeowners switch to solar to save money. Some cit...

Jeffrey Hebrank wants to install solar panels on his Highland home to take advantage of federal, state and regional incentives that have created something of a solar boom in Illinois. But a city fee of $25 a month would reduce the savings on his power bill and extend the time it would take to recoup his investment. ”Highland owns its own municipal power plant, so they don’t want us to install solar panels and generate our...

Planned Cincinnati Solar Project Could Be Largest ...

Cincinnati is trying to figure out where to put lots of solar panels in what could be the largest solar project on city owned property in the U.S. This picture is of existing solar panels on Beekman St. provided The City of Cincinnati is expected to put out a request for proposals next month in what could be the largest solar array by a city on city property. The 25 mega-watt project would power 25 percent of the...

Appalachia Could Get a Giant Solar Farm, If Ohio R...

AEP’s plan would bring jobs to an impoverished region, but its structure would break the established regulatory mold in a state that has pushed back on renewables. Appalachian Ohio, a region hurt by the decline of coal, may become home to one of the largest solar projects east of the Rockies. American Electric Power submitted a plan Thursday evening to work with two developers to build 400 megawatts of solar in...

Designing Greener Streets Starts With Finding Room...

City streets and sidewalks in the U.S. have been engineered for decades to keep vehicle occupants and pedestrians safe. If streets include trees at all, they might be planted in small sidewalk pits, where, if constrained and with little water, they live only three to 10 years on average. Until recently, U.S. streets have also lacked cycle tracks—paths exclusively for bicycles between the road and the sidewalk, protected from...

100% Renewable Energy: Cleveland Sets a Big Goal a...

Cleveland joins more than 80 U.S. cities that have committed to get all their electricity from renewable sources. But in Ohio, that might be easier said than done. Cleveland’s climate action plan includes improving energy efficiency in buildings to help lower electricity demand as it shifts to 100 percent renewable power. Credit: Chris Gent/CC-BY-SA-4.0 Cleveland, Ohio, which has worked for years to reinvent itself as...

Decentralized micro-grids could be the next big th...

A new report concludes that microgrid technologies could make a local “techno-economy” 90 percent self-sufficient, paving the way for a truly renewable society. When it comes to renewable energy, it’s not just about getting the energy — distribution and storage are also major issues. Renewable energy tends to be abundant during some parts of the day (for instance, when it’s sunny or windy), and lacking during other parts....

Solar energy tour designed to shed light on green ...

2018 Green Energy Ohio Tour 1. The Green Energy Ohio Tour Now in its 16th year, the Green Energy Ohio (GEO) will take place the weekend of September 28-30. Last year’s Tour featured 71 open houses and 6 guided tours, showcasing 10 different green energy technologies. Over 300 participants took advantage of the opportunity to see firsthand the progress that is being made in Ohio. We are looking forward to another great Tour –...
