Most of today's batteries are made up of rare lithium mined from the mountains of South America. If the world depletes this source, then battery production could stagnate.

Sodium is a very cheap and earth-abundant alternative to using lithium-ion batteries that is also known to turn purple and combust if exposed to water—even just water in the air.

West Antarctic Ice Melt Poses Unique Threat to U.S.

           

Sea level rise contributions from ice melt in different areas, including Greenland (a), West Antarctica (b), East Antarctica (c) and median of global glaciers (d). Values are ratios of regional sea level change to global mean sea level change. Adapted from Kopp et al. 2015.

News of Antarctica's accelerating ice melt garnered worldwide headlines yesterday, as scientists revealed that 3 trillion tons of ice has been lost to the sea since 1992 — mostly from the thawing West Antarctic Ice Sheet and Antarctic Peninsula.

Why it matters: The location of the ice melt is important for determining the future of coastal communities, according to climate scientists. And, due to West Antarctica melting, it turns out that the U.S. coastline will be hit extra hard . . .

Hurricanes Are Strengthening Faster Than They Did 30 Years Ago

With the start of hurricane season just three weeks away — and memory of last year's disastrous storms still fresh — scientists reported that powerful hurricanes are strengthening faster than they did 30 years ago.

Four of the monster hurricanes last year (Harvey, Irma, Jose and Maria) all intensified rapidly — when the maximum wind speed increases at least 29 mph within 24 hours . . .

 . . . According to a study out this week, the main cause appears to be a natural climate phenomenon that warms the seawater where hurricanes typically intensify in the Atlantic.

How Storms, Missteps and an Ailing Grid Left Puerto Rico in the Dark

           

A transmission tower and downed lines in the mountainous terrain of eastern Puerto Rico. Workers from the island and throughout the United States have worked to restore power after Hurricanes Irma and Maria last September.

It took months to restore electricity in Puerto Rico after hurricanes dealt a one-two punch. Many homes are still without power, and the system’s future is far from certain.

 . . . After Maria and the hurricane that preceded it, called Irma, Puerto Rico all but slipped from the modern era . . .

 . . . an examination of the power grid’s reconstruction — based on a review of hundreds of documents and interviews with dozens of public officials, utility experts and citizens across the island — shows how a series of decisions by federal and Puerto Rican authorities together sent the effort reeling on a course that would take months to correct. The human and economic damage wrought by all that time without power may be irreparable.

Wind and Solar Costs Continue to Drop Below Fossil Fuels. What Barriers Remain for a Low-Carbon Grid?

           

Energy Innovation's Michael O'Boyle and Silvio Marcacci outline the barriers to high-penetration wind and solar in the least-cost era

The following is a viewpoint from Michael O'Boyle, electricity policy manager for Energy Innovation, and Silvio Marcacci, communications director for Energy Innovation

utilitydive.com - by Michael O'Boyle, Silvio Marcacci - March 21, 2018

Wind and solar are now cheaper than virtually anyone predicted, and renewable technologies have reached an inflection point: Rapid cost declines made renewable energy the cheapest available sources of new electricity, even without subsidies, in 2017.  In many locations across America, building new wind energy projects is cheaper than running existing coal-fired power plants.

Seabed Mining Can Decide the Fate of the Deep Ocean

At the International Seabed Authority’s ocean-side headquarters, delegates from dozens of countries strolled through breezeways adorned with the works of Jamaican artists as the United Nations-chartered organization’s annual meeting began its second week. No one, however, was entering a conference room where the seabed authority’s Legal and Technical Commission (LTC) was in session and men in dark suits stood watch. A sign advised that the meeting was "closed."

Behind heavy wood doors, the 30 members of the commission convened in secret to discuss, among other things, confidential contracts issued to corporations and state-backed companies to explore and potentially mine vast, barely explored deep-sea habitats that scientists believe play a key role in the global ecosystem.

Scalable Water Management Solutions for Developed & Developing Cities

           

Cape Town, South Africa

meetingoftheminds.org - by Manohar Patole - April 3, 2018

The growth of urban settlements is subject to a range of factors influenced by demographic, economic, political, environmental, cultural, and social factors. Weather variability, or climate change, has recently risen up this list. These two factors: climate change and urban population growth, are dramatically affecting urban water management. On one hand, growing populations increase urban water demand and on the other, climate change has increased water variability (volume, distribution, timing and quality) . . . 

 . . . How will cities adapt? Reframe. Develop new responses.

Valuing the Resilience Provided by Solar and Battery Energy Storage Systems

submitted by John Cooper

                                     

cleanegroup.org

Summary:

Researchers from NREL and Clean Energy Group found that placing a monetary value on the ability of solar+storage to avoid losses during grid outages can significantly impact project economics and system design. Using data from Southern California Edison, researchers analyzed the economic case for solar+storage for three customer types (school, office building, and hotel) in Anaheim, California. In each case analyzed, larger PV and battery storage systems were found to be economical when the value of resilience is accounted for.

Pittsburgh's Microgrids Technology Could Lead The Way For Green Energy

           

Gene Lutz drives an electric fork lift powered by renewable energy at Pitt Ohio, a trucking company with an office in Harmar, Pa. The firm has invested in solar and wind energy, along with a bank of storage batteries, to create an independent microgrid that would hold up in a storm. Researchers hope to build more of these and link them together to create a reliable backup supply.  Daniella Cheslow/NPR

When President Donald Trump announced the U.S. would withdraw from the Paris climate accord, he said he represented "Pittsburgh, not Paris."

Pittsburgh Mayor Bill Peduto disagreed. He traveled to Germany this week as part of an unofficial delegation of more than 100 Americans, American officials and business owners who say they are still committed to climate talks taking place in Bonn. One element of Pittsburgh's climate strategy has been encouraging innovation in a technology known as microgrids.

Costa Rica has charted another clean energy accolade. So far this year, the Central American country has run on 300 days of 100 percent power generation from renewable energy sources, according to the Costa Rican Institute of Electricity (ICE), which cited figures from the National Center for Energy Control. . . .

 . . . Costa Rica currently receives 99.62 percent of its electricity from five renewable sources, the highest proportion since 1987. This year, 78.26 percent of electricity came from hydropower, 10.29 percent from wind, 10.23 percent from geothermal energy and 0.84 percent from biomass and solar. 

Costa Rica has emerged as a global environmental leader, with its frequent 100 percent renewable energy streaks and its 2021 goal of becoming carbon neutral—a deadline set a decade ago.
