Attorneys general from 17 Democratic-led states and the District of Columbia filed a lawsuit Monday against the Trump administration, asking a district court to block the president’s ban on wind energy approvals and declare it unlawful.

A group of Bryn Mawr math majors partnered with PSEA last year to help schools do the preliminary solar audits and analyses needed to determine whether the school district should invest in on-site solar.  The students caught on so quickly to all the online modeling tools, the Solar Schools Toolkit and its proformas that they were able to complete detailed analyses for two School Districts.  Two of the students stayed with the project after the semester had ended and took it all the way to the finish line, with the School District deciding to go solar on an elementary school. 

Electricity customers in the Pennsylvania-New Jersey-Maryland (PJM) region are facing a looming cost crisis stemming from two major issues: (a) worsening barriers to building and connecting new generation resources needed to supply the electric grid, and (b) unprecedented increases in projected electricity demand. Accelerating new resource deployment will be necessary to reliably serve new and existing load without greatly increasing energy costs to electricity customers.

Renewable energy companies are shifting strategy under President Trump, emphasizing the economic benefits of low-carbon electricity.

Akira Drake Rodriguez, a University of Pennsylvania professor who has studied inequities in housing and schools, has repeatedly visited a school in west Philadelphia to install weather sensors. Kids there were hot and frustrated, squeezed into overcrowded classrooms, and unable even to get a drink of water because school water fountains didn’t work.

“Every time I walked through that school, whether it was June or October, the kids were like, ‘It’s so f-ing hot in here,’” she said.

Reducing Industrial Sector Emissions in Pennsylvania (RISE PA),  is a $396 million industrial decarbonization grant program at the Pennsylvania Department of Environmental Protection.

The goal of RISE PA is to substantially reduce emissions from Pennsylvania’s industrial sector by funding decarbonization projects at industrial facilities across the Commonwealth.

We explore some of the ways of deploying solar energy for groups of people and how to make them successful.

Anna Goldman, a primary care physician at Boston Medical Center, got tired of hearing that her patients couldn't afford the electricity needed to run breathing assistance machines, recharge wheelchairs, turn on air conditioning or keep their refrigerators plugged in. So she worked with her hospital on a solution.

A new study finds rooftop solar will save California $2.3B this year — a rebuttal to the ​‘cost-shift’ math that’s led regulators to stifle solar growth.

For years, California utilities, regulators, and consumer advocates have argued that residents with solar panels on their rooftops are making electricity more expensive for everyone else in the state.

Five governors are urging the PJM Interconnection to reform its capacity market rules and interconnection queue process to prevent “unnecessary” costs for electricity customers.

The sector is enjoying massive production investment thanks to the clean energy law, even as it contends with heightened tariffs.

As the school year kicks off, many Philadelphia students are returning to aging buildings that are powered by an electric grid fueled largely by planet-warming natural gas.

David Hammes, from Exact Solar, explains that the solar systems on these affordable home ownership row homes will offset over 70% of the new low income homeowners' electricity use.  The homes are Energy STAR certified, all electric, with high efficiency heat pumps, heat pump water heaters, high levels of air sealing and insulation and many other measures. 

Inspired by Swedish youth activist Greta Thunberg, the Barrington Environmental Establishment has earned an EPA award.

BARRINGTON, R.I. — Four Barrington High School students, inspired by the 2019 protests led by Swedish youth activist Greta Thunberg, started a club they hope will endure long after graduation.

Emma Pautz, Abigail Goblick, Siddharth Gupta, and Mia He noticed the impacts of flooding and extreme weather in their hometown and founded the Barrington Environmental Establishment (BEE) to foster environmental change.

More homeowners are opting for heat pumps, once thought to be ill-suited to cold Northeast winters.

For decades, Scott Nelson’s Oceanside Service has been installing traditional residential cooling systems and gas-powered furnaces in Jersey Shore communities such as Long Beach Island.

Governor Josh Shapiro joined Department of General Services (DGS) Secretary Reggie McNeil, Constellation President & CEO Joseph Dominguez, and Lightsource bp Senior Vice President Alyssa Edwards to unveil the Commonwealth's renewable energy initiative, the Pennsylvania Project to Utilize Light and Solar Energy (PA PULSE).

…Improves Grid Reliability, Lowers Consumer Costs, Generates Jobs; Or Upends Competitive Markets And Is A ‘Death Wish’ For Our Economy (?)

Economic development projects shape the landscape and impact everyday life by influencing air quality, traffic volume, stormwater flow, and local employment opportunities.

Economic development can bring massive benefits to our communities, but it also brings other consequences that must be considered. These social and environmental considerations are known as "externalities."

US public education infrastructure faces significant challenges due to years of deferred maintenance and the growing impacts of climate change. Luckily, the Inflation Reduction Act offers substantial, easily accessible financial assistance to schools in the form of direct-pay tax credits for climate-friendly upgrades.

An amazing energy production milestone was just passed. The seven biggest solar companies now provide more usable energy than the fossil fuel giants of "Big Oil".

What? Can this really be true? Yes, it can, if you compare the amount of useful energy that goes towards the desired output of the end-use application. It may sound complicated, but it's actually a fair way of comparing the two energy sources.
