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 - 0 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... - 0 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.

Equinor: Floating Wind Farms a Natural Fit for Oil and Gas Companies | Greentech Media - 0 views

  • Wood Mackenzie expects 350 megawatts of floating offshore wind in operation by 2022 at various demonstration projects, and up to 10 gigawatts by 2030 with the right policy frameworks in place. Europe currently has a total of less than 50 megawatts of floating wind installed.

Growth of solar energy is not in line with the needs for ambitious energy transition | ... - 1 views

  • With an installed capacity of 117 GW at the end of 2018, the EU further lost ground in the worldwide market.
  • According to a recent 100% RES scenario of the Energy Watch Group, the EU needs to increase its PV capacity from 117 GW to over 630 GW by 2025 and 1.94 TW by 2050 in order to cover 100% of its electricity needs by renewable energy.
