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.

WoodMac: 'Final Wave' of Consolidation Hits Onshore Wind as Market Approaches Maturity ... - 2 views

  • Wind turbine makers and project developers will continue to introduce new technologies and cut costs, but “constraints on technology innovation are on the horizon,” at least for onshore wind farms, WoodMac said Wednesday, highlighting key trends for the industry.
    Will we see a future of photovoltaics onshore and wind offshore?

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 | ... - 3 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.

Want To Limit Global Warming? Electrify Everything, Finds Study | CleanTechnica - 8 views

  • Researchers at the Lappeenranta-Lahti University of Technology (LUT) in Finland and Energy Watch Group (EWG) have completed a 4½ year study that examined how to meet the goals of the Paris climate accords without such measures as carbon capture and geoengineering. Their conclusion? Run everything on electricity and generate all of that electricity using renewables, primarily solar.

Affordable, self-heating homes of the future, inspired by the past - - 2 views

    "Thick walls (with 10 inches of insulation, in Bayside Anchor's case) and triple-pane windows keep the building airtight so very little heat escapes. Instead of a central heating system, each apartment has a small electric baseboard heater."

139 Countries Could Transition to 100% Renewable Energy Under New Plan - NBC News - 5 views

  • A team headed by Stanford’s Mark Z. Jacobson outlined plans for 139 nations to transition to 100 percent clean, renewable energy by the year 2050.
  • The shift would also allow the countries to avoid the 3 percent they now spend in their Gross Domestic Products to address the costs of air pollution — mainly in the form of higher health care spending.
  • The plan maps each country and the energy sources it would rely on to reach the 100 percent renewable goal. Water-bound and geologically active Iceland would get 28 percent of its power from hydroelectric sources and nearly 23 percent from geothermal. Parched and wide-open Australia would get nearly 45 percent of its power from wind farms. Poland would get nearly two-thirds of its power from the wind.

  • The paper envisions a world of rapid technological change and a shift in which electricity replaces coal, oil, and gas. Fully implemented, the plans anticipates that 57.6 percent of that electricity would come from solar, 37.1 percent from wind and the rest from a combination of hydroelectric, geothermal, tidal and wave energy.
