The Next Renewable Energy Source Could Be Rain

Article | February 17, 2020

The quest for the next source of renewable energy is well underway, with no natural phenomenon overlooked. We have already harnessed the power of flowing water, wind, and sunlight, and the search for the next clean source of energy is far from over. The latest potential breakthrough in renewable energy comes in the form of rain. The rain has not been getting a lot of attention in renewable energy circles perhaps because it would be challenging to harness its electricity-producing potential. Yet attempts are being made, and in the latest breakthrough, U.S. and Hong Kong researchers have managed to produce 140 volts of power from one single raindrop. That’s enough to light 100 LED lights for a short while.

How EV Chargers Help Campus Energy Ecosystems Evolve

Article | March 6, 2020

Electric engines are incredibly efficient, getting useful work out of 85 percent of the energy that goes into them. Gas engines only get 30 percent, wasting a lot of the energy we pay to fill them up with. That one fact drives intense fuel cost savings for electric vehicles, a clear win for a campus shuttle and bus conversion. But switching from gas to electric also opens up a world of operational resilience, energy independence and sustainability — with the right implementation of electric vehicle charging technology.

Coronavirus Pandemic Impacting Solar, Storage and other Energy Sectors

Article | March 17, 2020

The COVID-19 pandemic has disrupted just about every sector of the economy, and that now includes the energy sector, according to analysts and media reports. Beyond just constricting demand, the virus had begun to undermine energy-related supply chains; the solar, utility storage and electric vehicle industries may be particularly hard hit, according to experts. The pandemic likewise threatens to divert regulatory attention from ordinarily pressing energy matters to other more urgent issues. Energy regulators in Texas and elsewhere, for instance, have ordered or encouraged utilities to suspend nonpayment disconnections because of the crisis.

Renewable Fuels Will Help Pave the Way to a 100% Renewable Energy

Article | April 10, 2020

The need to reduce carbon emissions is real. In 2018, the International Panel on Climate Change (IPCC) reported that global emissions would need to reach net-zero (or carbon-neutral) by 2050 to prevent severe climate change impacts. Electricity is a major contributor—electricity generation was responsible for approximately 33% of total CO2 emissions in the U.S. in 2018. Electric utilities stand to play a critical role in reducing carbon emissions. Many are up to the task of decarbonizing their operations and supplying carbon-free or carbon-neutral energy to their customers.
