Nuclear Fusion — Coming Soon To An Electrical Grid Near You?

Nuclear Fusion — Coming Soon To An Electrical Grid Near You?

   by  There are two kinds of nuclear power — fission and fusion. Fission is the one we are most familiar with. It involves splitting atoms — isotopes of uranium being the most common — in a process that releases large amounts of heat. That heat is then used to turn water into steam which is then used to drive fairly conventional turbines to generate electricity.The Commonwealth Fusion Systems tokamak. Credit:Fusion is the obverse of fission. Instead of splitting atoms, it . In theory, the result is more heat than is needed to keep the process going and that excess heat can be used to turn...

Re-powering — It’s The New, New Thing For Existing Wind Farms

Re-powering — It’s The New, New Thing For Existing Wind Farms

   by  There’s a new phenomenon sweeping the world of wind power — re-powering. Simply put, wind turbines today can generate quite a bit more electricity than they could a decade ago. The pylon that supports them really doesn’t care what kind of machinery is on top of it. Take down the old, put up the new, and enjoy the advantages of the most modern technology.That’s what’s happening in Texas these days, where has just finished re-powering the Langford wind farm, which was built in 2009. Now that its turbines have been replaced with state of the art equipment from GE Renewable Energy, its...

Volkswagen & Greece Bringing Climate Neutral Mobility To A Mediterranean Island

Volkswagen & Greece Bringing Climate Neutral Mobility To A Mediterranean Island

   by  What could be better than a tranquil Greek island in the Mediterranean Sea? A tranquil Greek island that is not enveloped in a cloud of carbon dioxide pollution from burning fossil fuels. Volkswagen and Greece have signed an agreement recently that will bring clean energy, electric vehicles, and state of the art mobility solutions to the island of Astypalea, a 100 square kilometer slice of heaven located south of Athens near the coast of Turkey.Credit:It has about 1,300 inhabitants but draws more than 70,000 tourists annually. The island aspires to become a pioneer for sustainable...

Tesla Expanding Into Solar Microgrids And Virtual Power Plants

Tesla Expanding Into Solar Microgrids And Virtual Power Plants

   by  Elon Musk says he expects Tesla’s energy business will one day be equal to or exceed its automotive business. That day may be some time in the future but the company is clearly expanding its solar and battery operations rapidly, both for grid scale and residential applications.Courtesy of TeslaLast week, Michael Snyder, Tesla’s director of engineering and construction for energy projects posted on , “If you like solving problems at the nexus of power systems interactions, protection coordination, system and product level controls, and DERs (Powerpacks, Megapacks, solar, and...

Solar, Storage, And Wind — Success Stories In Australia, US, And Vietnam

Solar, Storage, And Wind — Success Stories In Australia, US, And Vietnam

   by  There is a problem that haunts traditional means of generating electricity — it takes years to design, build, and activate any coal or gas powered facility. Building a nuclear power plant can take a decade or more. But renewables — especially solar — can come online quickly. Take the new 450 MW Trung Nam Thuan Nam Solar Plant, in Vietnam’s southeastern province of Ninh Thuan, which may be the largest solar power plant in the country according to .Courtesy of Trungnam GroupThe Trungnam Group says it completed that project in just 102 days after the financing was approved. A veritable...

Mercedes Says 6 New Battery Electric Models Are Coming Soon

Mercedes Says 6 New Battery Electric Models Are Coming Soon

   by  Mercedes Benz has yet to fully embrace the EV revolution. Although it has some battery powered models, they are not built on a dedicated electric car platform. That will change in 2021 when the company begins offering cars based on a new dedicated electric car platform that is scalable in every aspect. It can be modified to suit a number of models with different lengths and widths, both sedans and SUVs. Developing such a flexible electric car platform rather than repurposing existing chassis that rely on gasoline or diesel engines is the first step in transitioning away from...

DOE Says Combining Floating Solar With Hydroelectric Could Provide 40% Of The World's Energy Needs

DOE Says Combining Floating Solar With Hydroelectric Could Provide 40% Of The World's Energy Needs

   by  A , which is part of the US Department of Energy, suggests that if floating solar panels are deployed on the more than 379,000 hydro reservoirs globally, the resultant hybrid systems could generate anywhere from 16% to 40% of the world’s demand for electricity. In a , the NREL says adding floating solar panels to bodies of water that are already home to hydropower stations could produce as much as 7.6 terawatts of potential power a year from the solar PV systems alone. That’s equivalent to 10,600 terawatt-hours of electricity annually. In comparison, global final electricity...

Rocky Mountain Institute Study Shows Renewables Are Kicking Natural Gas To The Curb

Rocky Mountain Institute Study Shows Renewables Are Kicking Natural Gas To The Curb

   by  After analyzing the most recent data from two of America’s largest electricity markets — ERCOT in Texas and PJM in the Northeast — the has come to a startling conclusion. Renewables are muscling in on natural gas as the preferred choice for new electricity generation. In fact, according to RMI, what happened to coal is now happening to gas. What is needed, the organization argues, is a move away from the monopoly markets that have been the norm in the utility industry for more than 100 years and toward more open competition. Because when renewables compete head to head with thermal...

It's Official — Consumer Reports Confirms EV Owners Spend Half As Much On Maintenance

It's Official — Consumer Reports Confirms EV Owners Spend Half As Much On Maintenance

   by  Data is king, and when it comes to information on the frequency of repairs on automobiles, has more data than anyone. For its , it did a deep dive into the data from its 2019 and 2020 reliability surveys of electric and gasoline powered vehicles. After crunching all the numbers, Consumer Reports says “drivers of electric vehicles are saving an average of 50% on maintenance and repair over the life of a vehicle compared to owners of gas-powered vehicles.”Credit:Chris Harto, CR’s senior transportation policy analyst, says: “Electric vehicle owners don’t need a coupon to get half-off...

Argonne National Lab Breakthrough Turns Carbon Dioxide Into Ethanol

Argonne National Lab Breakthrough Turns Carbon Dioxide Into Ethanol

   by  Wouldn’t it be wonderful if we could do something useful with excess carbon dioxide other than deep in the bottom of the ocean? Scientists at Argonne National Laboratory may have discovered a way to do precisely that.Image credit:According to a from ANL, researchers at the lab, working with partners at Northern Illinois University, have discovered a new electrocatalyst that converts carbon dioxide and water into ethanol with very high energy efficiency, high selectivity for the desired final product, and low cost. Ethanol is a particularly desirable commodity because it is an...
