Sentences with phrase «over fossil fuels remains»

Not exact matches

The potential for efficiency remains enormous, and given the likely improvements in technology and changes in societal norms over the next century which it will take us to do the right thing, we are likely to be able to cut fossil fuel use further than most people imagine possible, even if renewables don't become commercially competitive (which wind is already, and solar is in certain situations).

Over the course of the past three years, overall CO2 emissions from the production of fossil fuels have remained flat while the economy has grown, on average, at a rate of 3.1 percent.

More 2014: In September, Neva Rockefeller Goodwin and others announced that the Rockefeller Brothers Fund would sell off its $ 45 million in fossil fuel investments, starting with coal and oil sands holdings, and shedding any remaining holdings gradually over several years.

The national survey by Pew Research Center, conducted March 27 - April 9 among 2,541 adults, finds pockets of partisan agreement over expanding solar and wind power, though wide political divides remain over increasing fossil fuels through such methods as coal mining, hydraulic fracturing and offshore drilling for oil and natural gas, a pattern consistent with a 2016 Pew Research Center survey.

Renewable energy is projected to be the fastest growing source of primary energy over the next 25 years, but fossil fuels remain the dominant source of energy.

While the above analysis yields good results for by tying past climate change to increases in human CO2 emissions, it should be cautioned that the suggested exponential time relation is not suitable for projecting the future over longer time periods, because of possible changes in human population growth rates and absolute limitations on carbon available in remaining fossil fuels.

At present consumption rates these remaining fossil fuels should last us over 300 years.

Contrary to what Peter Taylor says in his book, it is well known that sulphate aerosols created in the atmosphere from fossil fuel combustion were a major influence on the small cooling trend from 1940, although uncertainties remain over the scale of the effect.

Over the past three years, global CO2 emissions from fossil fuels have remained relatively flat.

Quantitative policy implications have been defined: coal emissions must be phased out over the next 20 years, and unconventional fossil fuels, such as tar sands and oil shale, must remain undeveloped.

These remaining fossil fuels should last us at least 200 to 300 years (probably much longer, as they get replaced by other sources over the next centuries).

While fossil fuels will remain an important source of energy, renewable energies will also gain importance, as a result of concerns over high fossil fuel prices, increasing greenhouse gas emissions and energy import dependence.

As climate alarmists rend their garments over fossil fuel emissions, a group of scientists has discovered that the world's plants have somehow increased their capacity to assimilate carbon, resulting in an actual decline in the percentage of human - produced CO2 remaining in the atmosphere.

A report published earlier this year noted that while a number of fossil fuel and utility companies have severed ties with the American Legislative Exchange Council over the group's controversial views on climate science and policies, Dominion remains a member.

While the cost of wind and solar energy is falling dramatically, which could lead to a major shift in infrastructure46, the fossil fuel industry remains remarkably resilient, subsidized, and still capable of tipping us over the limit47.

A 3 % discount factor with an hypothesis of $ 250 bn annualy has in fact a $ 8 trillion dollar policy cost (fared in todays dollar value) and not $ 20 trillion over 87 years; (ii) I would assume, with great certainty, that the cost of the policy will not remain at $ 250 bn (in 2013 $) in the coming 87 years: government feed in tarifs and green certificate subsidies will become less and less expensive with renewable energy prices matching fossil fuel energy prices in the coming decades.

The remaining 9 W m − 2 forcing requires approximately 4.8 × CO2, corresponding to fossil fuel emissions as much as approximately 10,000 Gt C for a conservative assumption of a CO2 airborne fraction averaging one - third over the 1000 years following a peak emission [21,129].

The remaining components of my plan, especially the strong fossil fuel demand reduction over and above that provided by the lifestyle maintenance component, provide the near term emissions reductions that offer any chance of avoiding the climate Apocalypse.

Fossil fuels not only provide the energy required for our manufacturing processes that alternatives will be hard - pressed (if even possible) to replace (including those needed to create the alternatives) but have been used to underpin much of the world's food production (while not particularly wise over the long - term, the world's population depends upon fossil fuel - based herbicides, pesticides, and fertilizers to remainFossil fuels not only provide the energy required for our manufacturing processes that alternatives will be hard - pressed (if even possible) to replace (including those needed to create the alternatives) but have been used to underpin much of the world's food production (while not particularly wise over the long - term, the world's population depends upon fossil fuel - based herbicides, pesticides, and fertilizers to remainfossil fuel - based herbicides, pesticides, and fertilizers to remain fed).
