Concentration of CO2 in the Atmosphere

July 23 Green Energy News

Opinion:

  • “Will the micro-grid put major power companies out of business?” There is now a range of units such as cogeneration plants, which deliver heat and electricity, wind turbines and solar PVs, owned by a whole raft of municipalities, households and businesses. [The Guardian]

Science and Technology:

  • A new material developed at MIT is able to convert 85% of incoming solar energy into steam — a significant improvement over recent approaches to solar-powered steam generation. Very little heat is lost in the process, and it can produce steam at relatively low solar intensity. [Energy Collective]

World:

  • Germany and the United Kingdom have 18 of the 30 most polluting energy plants in the European Union, according to a study funded by the European Union. All of the EU’s most polluting plants are coal-fired. [EurActiv]
  • Toyota will have at least three production fuel cell hybrid electric vehicle models on sale within ten years. That’s the official word from the company’s US National Manager Advanced Technology Vehicles, Craig Scott. [Motoring]
  • Australia’s household solar revolution has caught the government-owned electricity sector by surprise. More than one million Australians have already installed solar panels on their rooftops, which has caused demand for electricity from the grid to plummet. [Huffington Post]
  • Clean energy investment continued to grow in the second quarter. Investment was up 9% at $63.6 billion during the April-June period, with China the largest investor followed by the US, according to the latest quarterly update from Bloomberg New Energy Finance. [Business Spectator]
  • Indian Railways is all set to give a push to its plans to generate renewable energy. The national transporter is planning to generate 20% of its total energy requirement from solar and wind energy over the next couple of years. [Financial Express]
  • The UK government will retain its 2023-27 target for cutting greenhouse gas emissions, resisting reported pressure to water it down. Current estimates are that UK and EU levels of ambition on carbon-cutting “are likely to be extremely close”. [Recharge]
  • Located in the Engadine Valley in Switzerland, Zernez has set the goal of using only renewable sources to meet its energy requirements for buildings in the municipality, thus reducing CO2 emissions to zero. [Nanowerk]

US:

  • California officials have ordered an emergency shut-down of 11 oil and gas waste injection sites and a review more than 100 others in the state’s drought-wracked Central Valley out of fear that companies may have been pumping toxic waste into drinking water aquifers there. [Resilience]
  • Consumers Energy is choosing four Michigan farms to produce renewable energy with anaerobic digesters. The farms could generate electricity under long-term contracts that total 2.6 MW, enough to power about 2,800 homes. [Your Renewable News]
  • The Los Angeles Department of Water and Power will hold a groundbreaking ceremony to mark the start of construction for the 250-MW Beacon Solar Power Project. This new solar array is an important component of LADWP’s complete power supply transformation. [Sierra Wave]
