A new way to store sustainable energy: 'Information batteries' -- ScienceDaily - 3 views

  •  
    "What if surplus renewable energy could be stored as computation instead? That's the thinking behind "information batteries," a new system proposed by Raghavan and Jennifer Switzer, a Ph.D. student from UC San Diego, published recently in the ACM Energy Informatics Review."

The Century-Old Renewable You've Never Heard Of - Eos - 1 views

  • President Jimmy Carter signed a bill calling for 10,000 megawatts of OTEC capacity to be up and running by 1999. Then oil prices stabilized, administrations changed, and other than a few demonstration projects, nothing happened.
  • “When people actually have to build stuff that’s got to survive in the ocean and be insured, costs double. Insurance premiums triple,” he said. “And all of a sudden, what looked good when you announced it, you can’t actually get finance to build.”
  • Binger added that many small island nations still haven’t recovered from the debt they incurred during the oil crisis that began in 1979.

Fostering Livelihoods with Decentralised Renewable Energy: An Ecosystems Approach - 0 views

  •  
    "Decentralised renewable energy solutions linked to livelihoods is an important step in maximising the benefits of energy access for socio-economic development. Renewables offer the opportunity to translate investments in electricity connections and kilowatt-hours into higher incomes for communities and enterprises, local jobs, greater adaptive capacity and overall well-being.

Energy Systems for Sustainable Prosperity | SpringerLink - 1 views

  • Ecologically sustainable energy technologies comprise renewable energy supply together with improved efficiency of energy conversion and use. Together they can mitigate the climate crisis, greatly reduce pollution of air, water and land, create more jobs than are lost in the fossil fuel industries they replace, and contribute to energy independence and social equity. The best technical energy supply strategy is transitioning fossil fuelled electricity to renewables, electrifying most heating and transportation, and producing fuels by using renewable electricity to make hydrogen and ammonia. This technological transition is necessary and urgent, but unlikely to be sufficiently rapid to avoid irreversible climate change. Substantial demand reductions are needed by rich countries, beyond the technological measures of energy efficiency. This would entail an end to growth in energy production, materials extraction, land clearing and population, that is, the creation of a steady-state economy within Earth’s biocapacity.

Wind power risks becoming too cheap, says top turbine maker, Energy News, ET EnergyWorld - 4 views

  • The head of Siemens Gamesa warned on Wednesday that a decade-long race to bring down the cost of generating wind power could not continue, as it would reduce the financial muscle of turbine producers to continue investing in new technologies.

    If we want innovation, reliability, longevity in renewables, too much focus on cost is likely to be counterproductive.

pm modi: India's ambitious climate goals: Why decarbonization of hard-to-abate sectors ... - 1 views

  • India’s energy sector emissions are dominated by emissions from electricity production, industrial and construction activities, and transportation (See figure). And while electricity production will drive significant carbon emissions reduction, the “harder-to-abate” transportation and industry sectors will hold the key to India’s net-zero goal, and more so the 1 billion tons reduction by 2030 goal.
  •  
    The way we look at emissions may be key to resolving the climate crisis. Interesting to observe that buildings do not even appear in the Indian taxonomy.

IDTechEx Predicts Electric Vehicle Charging Going Zero-Emission, Off-Grid - 5 views

  • The new IDTechEx report, "Zero-Emission Electric Vehicle Charging: Off-Grid 2020-2040" examines how the electric vehicle business is finding it profitable to respond to criticism that clean vehicles should not be charged with fossil fuel electricity. The purpose of this 230-page report is to enable materials, component, vehicle and infrastructure suppliers and putative suppliers, and all others in the value chain, to understand this large emerging opportunity for off-grid zero-emission OGZE charging of electric vehicles land, water and airborne.

IRENA Director-General Statement on Oil Prices and Impact on the Renewable Energy Sector - 2 views

  • Oil plays a negligible role in power generation and therefore does not compete with renewables in this respect. Renewables have become the dominant source of new power generation capacity over the last six years because they are competitive at the bottom end of the conventional fossil fuel power generation cost range – primarily with coal.
  • Oil plays a much more important role in the transport sector, which accounts for half of total demand, and where without low-emission transport policies in place, an extended period of low oil prices, may impact the speed of electric vehicle adoption.
  • Conversely, oil price volatility may undermine the viability of unconventional oil and gas resources as well long-term contracts, providing a window of opportunity to reduce or redirect fossil fuel subsidies towards clean energy, while minimising the potential of social disruption.

  • What is critical to understand, is that the long-term planning horizons involved, and the momentum that currently exists in the energy transformation, means neither low oil prices nor COVID-19 will interrupt or change our path towards decarbonisation of our societies and towards the achievement of the sustainable development goals.

Carbon Pricing as a Policy Instrument to Decarbonize Economies | Energy Central - 1 views

  • The study analyzed the jurisdictional characteristics of 37 countries where carbon pricing mechanisms – both carbon taxes and cap-and-trade schemes – have been implemented or proposed as a means to support decarbonization.
  • Carbon leakage does not appear to represent an economically significant obstacle.

Offshore Wind Could Power Coastal China - Study | Offshore Wind - 2 views

  • The total generating potential from wind farms built along the Chinese coast is 5.4 times larger than the current demand for power in China’s populous coastal provinces, a study by Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and Huazhong University of Science and Technology in China shows

New Publication on Chinese Climate Change Policy | Energy Central - 0 views

  • But sub-national governments can also significantly advance efforts to mitigate climate change. Provinces and municipalities around the world have indeed undertaken initiatives – sometimes working together across national boundaries – to reduce greenhouse-gas emissions. This includes jurisdictions in the largest-emitting countries – China, the United States, and India – as well as in the European Union.

Minister: Germany should start world's first green-hydrogen tender next year | Recharge - 0 views

  • The German environment minister has called for the world’s first green-hydrogen tender to begin next year, starting at 5,000 tonnes and rising by the same amount each year until 2030, when 5GW of electrolysis capacity would be installed.
  • According to Recharge calculations, every 5,000 tonnes of green H2 would require about 250GWh of renewable energy, the equivalent of 79MW of offshore wind (at a capacity factor of 36%) or 130MW of onshore wind (capacity factor of 22%).

Energy Efficiency, Natural Gas and Renewable Energy Drove Decade of U.S. Energy Transfo... - 1 views

  • The 2020 Factbook showcases the impact of sustainable energy over the last decade and highlights findings for 2019 that follow the macro trends of the 2010s: • Renewable energy became the cheapest new generation source in many U.S. power markets. The U.S. has over 2 times more renewable power generating capacity today than a decade ago. Solar capacity in 2019 was 80 times greater than what it was at the end of 2009. • Energy efficiency choices have proliferated, with federal programs helping high-efficiency appliances reach mass markets and state codes bolstering building efficiency. The economy grew every year in the past decade and energy use fell in five of the ten years. U.S. energy productivity (GDP/energy consumption) improved 18% between 2010 and 2019, benefiting businesses and households. • Natural gas became the primary source of U.S. power generation and shifted the scales in the global market. Between 2010 and 2019 domestic natural gas production jumped 50%, and natural gas went from providing 24% of the nation's electricity to 38%. The U.S. increased its export capacity to exceed its import capacity, building stronger trade relationships around the world. In 2019, the U.S. exported more gas than it imported.
