Do you have a segregated curve by fossil fuel type?

Not exact matches

The scientists have devised a new manufacturing technique that could boost the efficiency of an inexpensive type of solar cell by up to 50 %, making the technology an economically feasible alternative to fossil fuels in the search for sustainable energy.

-- Within 6 months after the date of enactment of this Act, and after opportunity for comment, the Secretary shall issue a final rule under this subsection for determining the level and type of fossil fuel - based electricity delivered to retail customers by each distribution utility in the United States during the appropriate period.

-- The owner or operator of any distribution utility that believes that the Secretary has misapplied the methodology in the final rule in determining the amount and types of fossil fuel electricity delivered by such distribution utility may seek rehearing of such determination within 30 days of publication of the determination in the Federal Register.

If it takes 100 plus years to double the concentration of CO2, and if the equilibrium response is a 2C increase (Pierrehumbert, «Principles of Planetary Climate», p 623), and if the increased CO2 produces increased vegetation and crop growth, then the present rate of development of non-fossil fuel power and fuel generation is more appropriate than an Apollo type project or attempt to get rid of all fossil fuel use by 2050 starting now as fast as can be done.

A full lifecycle analysis of Bio-SNG production undertaken by North Energy Associates found that for many types of feedstock, the lifecycle CO2e savings of Bio-SNG compared with fossil fuel alternatives are typically ~ 90 %.

Meanwhile, other types of aerosols, often produced by burning fossil fuels, can change surface temperatures by either reflecting or absorbing incoming sunlight.

Requires the Secretary to: (1) issue a rule for determining the level and type of fossil fuel - based electricity delivered to retail customers by each distribution utility in the United States; and (2) make annual determinations of the amounts and types for each such utility and publish them in the Federal Register.

(i) determined by the amount and types of fossil fuel - based electricity delivered directly to all retail customers in the prior calendar year beginning with the year ending immediately prior to the period described in subsection (b)(2); and

A common myth is that because some types of renewable energy do not provide baseload power, they require an equivalent amount of backup power provided by fossil fuel plants.

The Zero Tool normalizes building performance by climate, space type, building size, occupancy, and schedule, allowing users to compare a new or existing building's fossil fuel energy consumption with other buildings.

And this is a common phenomena by many who engage in similar types of activism against fossil fuels.

Atmospheric CO2 is likely to increase to around 640 ppmv *, assuming — There will be no global Kyoto type climate initiatives — Human CO2 emissions increase with human population — Global per capita human fossil fuel use increases by 30 % by 2100 (it increased by 20 % from 1970 to today)-- Population growth is estimated to slow down sharply, with population reaching 10.5 billion by 2100 (* Note that this could be lower by around 60 ppmv if there is a concerted switch to nuclear power instead of coal for new power plants)

The most water - efficient energy sources are natural gas (though we may be just about out of it) and synthetic fuels produced by coal gasification; the least efficient are ethanol and biodiesel — the biofuels just can't catch a break these days, can they?Water use winners and losers The research pair analyzed 11 types of energy sources, including coal, fuel ethanol, natural gas, and oil; and five power generating methods, including hydroelectric, fossil fuel thermoelectric, and nuclear methods; in terms of power generation, Younos and Hill have found that geothermal and hydroelectric energy types use the least amount of water, while nuclear plants use the most.

Global CO2 emissions from fossil fuel and industry since 1960 (top left); global emissions by fuel type (middle left); Territorial (solid) and consumption (dashed) emissions by country group (bottom left); territorial emissions from biggest emitters (top right); per capita emissions from biggest emitters (bottom right).

They see climate change — driven by rising concentrations of atmospheric carbon dioxide, in turn fuelled by ever - greater fossil fuel combustion — as an emerging «mega-disturbance»: the bringer of not just longer and hotter droughts but of a new class of affliction, the unprecedented «global - change - type drought».
