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. Wind beats coal by any environmental measure, but that doesn’t mean that its impacts are negligible. Source: Miller and Keith (2018a).
Schema of synfuel synthesis through solar-driven biomass gasification. Solar energy produces both heat for gasification and H 2 via electrolysis. High temperature heat for biomass gasification is obtained from a molten-salt system in a solar concentrating tower. Land area for solar energy collection (m 2 /ton fuel/yr).
And no one touches me more deeply when I hear him sing it then another great patriot who has devoted most of his life to selflessly working on the environment and justice issues I care about – Jackson Browne. . Little Stevie Van Zandt wrote the lyrics to the song I consider MY national anthem.
Natural gas will play a leading role in reducing greenhouse-gas emissions over the next several decades, largely by replacing older, inefficient coal plants with highly efficient combined-cycle gas generation, according to a major new interim report out from MIT. The first two reports dealt with nuclear power (2003) and coal (2007).
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. Only when wind replaced coal itself did social costs decrease.
After a decade in the solar power installation business, Bradley Bartz is tired of being Mr. Nice Guy. He’s filed suit against Torrance, the proud home of Exxon/Mobil’s refinery, for stopping him from installing solar panels in the Hillside Overlay district. “ Idiots ! “ Idiots !&#
Whatever the future energy mix, it''s becoming apparent that coal and gas are both hugely consumptive and not entirely great for the environment--even if they provide large swathes of the world with their energy.
According to a new survey from Pike Research, US consumer support for renewable energy sources, such as solar and wind, is high while support for cap and trade as a carbon management scheme is extremely low. Clean Coal: 47%. —Energy & Environment Consumer Survey. —Energy & Environment Consumer Survey.

Electric vehicles charged in coal-heavy regions can create more human health and environmental damages from life cycle air emissions than gasoline vehicles, according to a new consequential life cycle analysis by researchers from Carnegie Mellon University. Fossil fuel plants are the ones dispatched in response to new charging load.
I’m not the least bit intimated or scared by any of the people now arguing against saving ourselves – whether they’re with the oil, coal or gas industries or in the highest reaches of the Republican Party or atop the US Chamber of Commerce. And I’m just the guy to tell that truth whether you want to hear it or not.
Topping the favorables were solar power (77% in 2011, down from 81% in 2009); wind energy (71% in 2011, down from 79% in 2009); and hybrid vehicles (61% in 2011, down from 70% in 2009). Favorability ratings of smart grid and clean coal were tied for the second largest decline, each falling 10 points over the two-year period.
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.
In a paper published in the journal Atmospheric Environment , they report on the findings from a suite of scenarios designed to quantify the effect of both the magnitude of EV market penetration and the source of electricity generation used to power them. coal, oil, natural gas, and biomass).

A comprehensive three-year scientific study into the air, water and soil impacts of hydraulic fracturing (HF) in coal seam gas (CSG) in Queensland, Australia has found little to no impacts on air quality, soils, groundwater and waterways. CSIRO scientist sets up a solar-powered air-quality-monitoring station in the Surat Basin, Queensland.
While more effort is needed to reach that goal, one energy organization has predicted that renewables will overtake coal generation as the world’s largest electricity source in early 2025. There are still some big hurdles to overcome, including the difficult global macroeconomic environment.” “For In the U.S.,
Primary energy sources in model include fossil fuels (crude oil, natural gas, and coal); non-renewable non-fossil sources (nuclear); and renewable sources (hydroelectric, wind, solar, and biomass). These energy sources can be converted to transportation fuels or used for generation of heat, electricity, or both (cogeneration).
A large part of this potential comes from six relatively standardized categories: solar and wind energy; efficient appliances; efficient passenger cars; afforestation and stopping deforestation. There are an estimated 6,683 operating coal-fired power plants in the world, with a combined capacity of 1,964 GW.

The 1,000 wind turbines that the spheres could anchor could, on average, replace a conventional on-shore coal or nuclear plant. The team hopes to extend its testing to a 3-meter sphere, and then scale up to a 10-meter version to be tested in an undersea environment, if funding becomes available.
As the percentage of electricity supply from wind and solar increases, grid operators will need to employ strategies and technologies, including energy storage, to balance supply with demand given the intermittency of the renewable supply. Coal- and natural gas-fired power plants are responsible for at least a third of those emissions.
