All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.
This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by a record 18% year-on-year to its lowest level since 1975. An increase in natural gas generation offset some of the climate gains from this coal decline, but overall power sector emissions still decreased by almost 10%.
New investment in wind, solar, and other clean energy projects in developing nations dropped sharply in 2018, largely due to a slowdown in China. This is due to wind and solar projects generating only when natural resources are available while oil, coal, and gas plants can potentially produce around the clock. thousand in 2017.
My favorite part of this next CicLaVia is t he Bike Parade coming from my friends at Greenpeace and Sierra Club which they’re calling ROLL AGAINST COAL. In case you didn’t know, the City of Los Angeles still gets 40% of its electricity from coal-fired power plants, the dirtiest polluters and greenhouse gassers on the planet.
CO 2 emissions from US coal-fired power plant could be phased out entirely by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade, according to a paper published online 30 April in the ACS journal Environmental Science & Technology.

” “ Some have even suggested that coal state representatives in Washington should block any advancement of national health care reform legislation until the coal industry’s demands are met by the EPA, ”, wrote Byrd. West Virginia is home to about 22,000 coal miners, down from 62,500 in 1979.
earlier post ), a new study by a team at Environmental Defense Fund finds that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. They also estimated emissions caused by flooding the reservoir.
The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5
This will include the “Wind Challenger”, a cargo ship design with a hard sail, which would reduce emissions by harnessing wind energy. MOL has been jointly studying the wind technology with cross-industrial partners. The first Wind Challenger is scheduled to be released in 2022.
Further, according to Rystad Energy, Big Oil is expected to pump in $166B into new oil and gas ventures over the next five years, thus dwarfing the currently specified outlay of just $18B (less than 10% of capex) for solar and wind energy projects. Good case in point: Italian multinational oil and gas giant Eni S.p.A. 2 Total SA.
Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost. —Mark Jacobson. —Mark Jacobson.

Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Preparing the US for the impacts of climate change. Earlier post.).
The technology group Wärtsilä has issued a report ahead of COP26, the UN’s Climate Change Conference to be held in Glasgow this autumn, describing the environmental and economic opportunities for states that decarbonize rapidly. coal and gas), significantly reducing the overall levelised cost of electricity.
Energy company RWE and steel producer ArcelorMittal have signed a memorandum of understanding to work together to develop, build and operate offshore wind farms and hydrogen facilities that will supply the renewable energy and green hydrogen required to produce low-emissions steel in Germany.
billion tonnes, their highest ever level, as the world economy rebounded strongly from the COVID-19 crisis and relied heavily on coal to power that growth, according to new IEA analysis. Coal accounted for over 40% of the overall growth in global CO 2 emissions in 2021, reaching an all-time high of 15.3 billion tonnes.
The President’s Council of Advisors on Science and Technology (PCAST) released a letter to President Obama describing six key components the advisory group believes should be central to the Administration’s strategy for addressing climate change. Both approaches are essential parts of an integrated strategy for dealing with climate change.
The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown. In 2005, noncarbon sources accounted for 28% of the US electricity mix.
Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either. Drivers of plug-in hybrid electric vehicles rely too much on the gasoline engine for this pathway to be a long-term climate solution, the ICCT said. Source: The ICCT.
million barrels per day from 2010 to 2040, including the production of both petroleum (crude oil and lease condensate, natural gas plant [NGPL], bitumen, extra-heavy oil, and refinery gains), and other liquid fuels (coal-to-liquids [CTL], gas-to-liquids [GTL], biofuels, and kerogen). trillion kilowatthours in 2010 to 5.5
The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers. —Daniel Kammen.
This year is pivotal for international climate action—and it began with high hopes—but these latest numbers are a sharp reminder of the immense challenge we face in rapidly transforming the global energy system. But our numbers show we are returning to carbon-intensive business-as-usual.
The Administration said the United States will submit its 2025 target to the Framework Convention on Climate Change as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015. launching a new track on the interaction of energy and water (the energy/water ‘nexus’).

CO 2 emissions from coal fell by 14.6%, the largest annual percentage drop in any fuel’s CO 2 emissions in EIA’s annual CO 2 data series dating back to 1973. The United States now emits less CO 2 from coal than from motor gasoline. Source: US Energy Information Administration, Monthly Energy Review.
solar, wind, hydroelectric, and nuclear) as compared to the eastern US (EUS), where the electricity market is dominated by pollutant and precursor emitting combustion sources (i.e., coal, oil, natural gas, and biomass). Locations with more coal-fired power in their energy mix experienced an increase in PM during the summer.
Russia-based Udokan Copper , the developer of Russia’s largest new copper deposit, outlined scenarios to cut the carbon intensity of copper production up to 75% by 2035, bringing the company closer to its ultimate goal of climate neutrality in the long run. In 2021, Udokan Copper invested RUB 764 million (US$11.5
Trestle and Larksen’s integrated approach furthers ethanol producers’ ability to scale up production of low carbon biofuels and allows existing power plants to generate electricity with the cost and reliability of coal and with carbon emissions similar to wind.
A typical electric car requires six times the mineral inputs of a conventional car, and an onshore wind plant requires nine times more mineral resources than a similarly sized gas-fired power plant. However, in climate-driven scenarios, these positions are reversed well before 2040. Source: IEA. Source: IEA.
However, the resulting low gas prices, as well as clean air and climate policies, will promote further switching to gas from other more polluting energy sources, such as oil and coal. The report shows that medium-term growth will come from increasing cost-competitiveness and increased global access to gas. MMbtu in Russia, $8.7/MMbtu
Wind and solar have been exhibiting very rapid growth, even as subsidies and support have in general become less generous, and that has been driven mainly by dramatic improvements to their cost-competitiveness, as well as by the removal of barriers such as grid bottlenecks. Oil at $60/barrel could mean a natural gas price as much as $0.90/MMBtu
Coal-powered synthetic natural gas (SNG) plants being planned in China would produce seven times more greenhouse gas emissions than conventional natural gas plants, and use up to 100 times the water as shale gas production, according to a new study by Duke University researchers published in the journal Nature Climate Change.
Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time.

Relying on a higher share of efficient, low-emission combined cycle power plants and wind energy could save €150 billion (US$200 billion) by 2030 while attaining the same CO 2 targets, Siemens says. The country should give greater priority to high-efficiency combined cycle power plants and wind power, the company suggests.
One of the other big business groups the WSJ is talking about is the motley group of US Senators and US Congress members who got their money directly from the oil, gas and coal industry. We’re going to end the use of coal in this country in the next ten years and we’re going to phase out the use of oil for transportation.
This was the result of growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, as well as structural changes in the global economy. The decline was driven by a surge in shale gas supplies and more attractive renewable power that displaced coal.
