Designing High Wind -Resilient PV Systems

Solar Under Storm Part II: Designing Hurricane-Resilient PV Systems February 17, 2020  |  By RMI, Laurie Stone and Christopher Burgess The last three years have seen major hurricanes wreak havoc on island nations. Hurricanes Harvey, Irma, Maria, and Dorian caused catastrophic damage to homes, infrastructure, and economies throughout the Caribbean basin. At the same time, the use of solar photovoltaic (PV) power …

Trees cool air, slow runoff, and boost students and public health. Should trees be seen as a public utility which all must be able to access?

Benefits of trees include slowing stormwater runoff, cooling air temperatures, and even boosting student achievement and public health. Trees capture more than a third of rainfall, according to the U.S. Environmental Protection Agency (EPA), easing the strain on flooding and stormwater infrastructure. Their shade helps lower energy use by nearly half, according to the EPA, while reducing carbon emissions by …

Blue Spaces: Why time spent near water is the secret of happiness

The Guardian| By Elle Hunt, November 2019 ‘People who visit the coast at least twice weekly tend to experience better general and mental health,’ says Dr. Lewis Elliott. James Galpin/Getty Images After her mother’s sudden death, Catherine Kelly felt the call of the sea. She was in her 20s and had been working as a geographer in London away from …

Researchers Propose Floating Microgrids and Virtual Power Plants Made up of Electric Boats

September 6, 2019 By Lisa Cohn, Microgrid Knowledge.com Electric boats may enable floating microgrids that could serve islands that have historically been powered by fossil fuels, according to a report from researchers at the University of New South Wales in Sydney, Australia. By Igor Karasi/Shutterstock.com “Powering small islands with reliable, affordable and green electricity is a big challenge due to their dispersed …

Alaska, Model of Microgrid Development, Delivers Resiliency in Cold, Remote Conditions. Largest battery and microgrid in the country (2003) has prevented 784 outages since it was first installed.

July 16, 2019 By Lisa Cohn, Microgrid Knowledge, Alaska, Model of Microgrid Development, Delivers Resiliency in Cold, Remote Conditions Alaska’s challenges — cold weather and the high cost of delivered energy — are part of the reason the state is a model of innovative microgrid development, with the largest number of microgrids in the US, at 122. “This innovation flows from both the …

Using distributed energy to lower peak demand, increase resilience, save money, and lower emissions: Utility found storage cheaper than a second power line

Can grid resiliency finally pay for itself? JULIAN SPECTOR GTM Research, JUNE 07, 2019 Eversource Wants to Back Up an Entire Rural Town With Batteries Large and Small 2 “This is not, strictly speaking, a resilience play — it’s using distributed energy to lower peak demand, thereby saving money and lowering carbon emissions“ The traditional option would be to build a …

Energy resilience planning on a local/regional basis in Colorado

Energy efficiency and solar coupled with storage are both examples of resilience options that can provide benefit year-round. While end-use efficiency does not in itself provide power during an outage, it allows for more critical services to be delivered with limited generation capacity. Year-round, increased efficiency lowers energy demand and costs. On-site solar and storage can provide backup power when the grid goes …

Part of world’s largest ice shelf melting 10x faster than the rest. Gorillas showing elevated stress levels in months with higher than average temperatures and rainfall

Part of the world’s largest ice shelf is melting 10 times faster than the rest, reports BBC News. A new study of Antarctica’s Ross Ice Shelf, published in Nature Geoscience, reveals that one area is melting due to warm ocean water getting into a cavity under the shelf. The rapidly melting zone is at the front of the Ross Ice …

Progress for whom, and 7 critical graphs showing why Steven Pinker is wrong

Progress for whom, and other critical questions Pope Francis insists we ask line up with points by and data from Jeremy Lent… In Enlightenment Now: The Case for Reason, Science, Humanism, and Progress, published last year, Steven Pinker argues that the human race has never had it so good as a result of values he attributes to the European Enlightenment of …
