The campus greenhouse gas reduction plan outlined in the report centers on four key approaches: reducing the overall energy use on campus, reducing the use of fossil fuels in campus buildings and vehicles, increasing the use of renewable energy sources to meet campus needs, and minimizing the release of «fugitive» gases from campus operations such as specialty research gases in laboratory buildings.

Such a hybrid infrastructure would lower the use of carbon fuels for the generation of electricity, because renewable energy can replace them if there is sufficient sun or wind available.

It stresses the good, such as «we will use and generate only renewable energy,» rather than the more commonly stated less bad; «we will reduce our use of fossil fuels.»

This is a regulation from EPA that forces states to reduce fossil fuel use in their electricity generation in favor of «renewables» such as wind and solar (but not hydro, which most environmental groups dislike, of course), whether they want to or not.

(Sec. 126) Amends the CAA to revise the definition of «renewable biomass» for purposes of the renewable fuel standard by expanding the amount of biomass from forested land that could be used to produce fuels under such standard and eliminating the requirement that feedstock crops come from previously cultivated land.

Using paper fiber as fuel reduces the amount of CO2 permanently released into the environment compared to the burning of fossil fuels, such as coal, that are not renewable.

There are immense direct and indirect public benefits in transitioning to an efficient renewable energy system in terms of reduced incidence of diseases such as asthma, freeing up of most of the supplies of water that are now used for thermal electricity generation (and hence reduced conflict over water), reduced air, water, and soil pollution that accompanies fossil fuel production, processing and use, and greatly improved prospects of avoiding the worst consequences of climate change.

Finally, it should be noted that socioeconomic hypotheses associated with the lower emission trajectories (such as the one commented upon by Tim Worstall) imply a greatly increased use of nuclear and fossil fuels, especially cooal and natural gas, and the share of renewable sources reaching much less than the «80 %» claimed by the recent «renewable energy» IPCC report.

ClearFuels expects that the life - cycle carbon footprint of renewable fuels produced by ClearFuels - Rentech technologies can be near zero, depending on the feedstock and the alternate use of such feedstock.

Getting greenhouse gas emissions to 60 percent below the 1990 level will require four types of measures: aggressive energy efficiency, aggressive electrification, decarbonizing electricity (such as by using renewable energy sources) and decarbonizing the remaining fuel supply (such as by using biofuels).

In any event, even using such inflated claims of «subsidies», on a joule / subsidy - cost basis, fossil fuels beat the snot out of renewables.

«The methodology can not be used to infer anything about the direct impacts of specific policies, such as power plant emissions limits or renewable portfolio standards, or the effect that changes in relative prices may have on fuel choice, such as the impact of the change in supply or price of natural gas or renewables may have had on the competitiveness of coal.

Since ethanol producers» goal is more ethanol use, and an EPA pullback on E15 would get in the way of that goal, attacks on both studies — such as those by the Renewable Fuels Association — aren't surprising.

This feat, according to the calculator, would require a series of massive changes to how we use energy, such as a shift from fossil fuels towards nuclear and renewables, and much wider use of electric heat and transport.

Renewable energy technologies produce clean energy, can be better scaled to meet demand than large dams, reduce dependence on problematic energy sources such as fossil fuels and large hydro, and can be used in rural areas far from the grid, where most of the world's un-electrified communities are located.

Important to note is the comprehensive breadth of sectors that fall under the «new energy» concept - its not just renewables such as wind, solar and biomass, but also energy efficiency, nuclear, smart (and strong) grid, transportation, unconventional natural gas, and more efficient use of fossil fuels.
