Largest combined wind/solar/battery plant opens in U.S.

Posted by in categories: energy, sustainability

Portland General Electric (PGE), a public utility, has partnered with NextEra Energy Resources to create a 350 megawatt (MW) clean energy project that combines wind, solar, and battery storage. Wheatridge Renewable Energy Facility, located at the northern edge of Oregon, has the capacity to serve 100,000 homes.

Although great progress is being made with scaling up renewables, intermittency remains a significant issue – since wind does not always blow, and the Sun does not always shine. Falling costs and improvements in technology mean that batteries are increasingly a realistic option for utilities, but we are still a long way from such systems being able to fully handle the demands of national electrical grids.

The newly operational Wheatfield facility is among the most notable advances in battery storage to date in the U.S. It consists of 120 turbines (a mix of 2.3 MW and 2.5 MW machines) generating 300 MW, alongside a 50 MW photovoltaic solar array, for a total of 350 MW. An accompanying battery storage facility is charged using power from the grid and provides 30 MW of continuous power for four hours, i.e. 120 megawatt-hours (MWh). When combined, this is enough to supply nearly 60% of the power generated by the Boardman Coal Plant, which became the last coal-fired plant in Oregon before its demolition a few weeks ago.

Tesla is finally going to expand Gigafactory Nevada

Posted by in categories: energy, sustainability, transportation

Tesla is finally planning to expand the Gigafactory Nevada building after years of being “stuck” at about “30% of its final size.”

Tesla Gigafactory Nevada was the first major step in Tesla’s effort to secure battery cell supply for its ambitious growth.

The automaker partnered with Panasonic to deploy new battery cell production capacity at the facility, and Tesla used those cells to build battery packs for its vehicles and energy storage products.

There Are Cheaper, More Sustainable Ways Than Desalination to Meet Our Water Needs

Posted by in categories: energy, sustainability

Desalination plants discharge brine and wastewater, which can also kill nearby aquatic life if the process is not done properly. And generating the large quantity of energy that the plants consume has its own environmental impacts until it can be done carbon-free, which is still years off in most cases.

Unaffordable Water From Costly Plants

MIT Engineers Build Wireless Underwater Camera That Doesn’t Need Batteries!

Posted by in categories: climatology, space, sustainability

New underwater camera could help scientists explore unknown regions of the ocean, track pollution, or monitor the effects of climate change.

More than 95 percent of Earth’s oceans have never been observed, according to estimates by scientists, which means we have seen less of our planet’s ocean than we have the far side of the moon or the surface of Mars.

Mars is the second smallest planet in our solar system and the fourth planet from the sun. It is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is prevalent in Mars’ surface resulting in its reddish color and its nickname “The Red Planet.” Mars’ name comes from the Roman god of war.

Tesla Solar Roofs Stand Up To Hurricane Ian, Elon Musk Sending Starlink Satellites To Help Florida

Posted by in categories: climatology, Elon Musk, internet, satellites, sustainability

Known for its electric vehicles, Tesla Inc TSLA also has a solar power division. Customers who bought solar roofs in Florida might be thanking the company after the lingering damage of Hurricane Ian.

What Happened: Hurricane Ian hit landfall in Florida and has caused severe damage to the region. Benzinga previously reported the impact could be $258 billion in replacement costs in one region and another $149 billion in the area of Tampa Bay.

The impact could be hundreds of millions of dollars for insurance companies as well.

Smart microrobots walk autonomously

Posted by in categories: robotics/AI, sustainability

A collaborative effort has succeeded in upgrading solar-powered microbots – each of which now has their own built-in, miniature computer – allowing them to walk autonomously and without being externally controlled.

Cornell researchers and others had previously developed microscopic machines able to crawl, swim, walk, and fold themselves up. However, these always had “strings” attached; to generate motion, they needed wires to provide electrical current, or laser beams focused directly onto specific parts of robots.

“Before, we literally had to manipulate these ‘strings’ in order to get any kind of response from the robot,” explained Itai Cohen, Professor at Cornell’s Department of Physics. “But now that we have these brains on board, it’s like taking the strings off the marionette. It’s like when Pinocchio gains consciousness.”

This 100% solar community endured Hurricane Ian with no loss of power and minimal damage

Posted by in categories: climatology, habitats, internet, solar power, sustainability

The streets in this meticulously planned neighborhood were designed to flood so houses don’t. Native landscaping along roads helps control storm water. Power and internet lines are buried to avoid wind damage. This is all in addition to being built to Florida’s robust building codes.

Some residents, like Grande, installed more solar panels on their roofs and added battery systems as an extra layer of protection from power outages. Many drive electric vehicles, taking full advantage of solar energy in the Sunshine State.

Climate resiliency was built into the fabric of the town with stronger storms in mind.
