The key to this process, according to Cambridge University’s Tony Wrigley, the great historian of the era, was the replacement of human- and animal-driven mechanical energy by more productive forms, such as coal and other fossil fuels.
Rich countries have embraced biofuels – energy derived from plants – to reduce their reliance on fossil fuels.
But the climate benefit is negligible: according to the International Institute for Sustainable Development, deforestation, fertilizer, and fossil fuels used in producing biofuels offset about 90% of the “saved” carbon dioxide.
The disappearance of polar ice is driven by the use of fossil fuels, which not only underpins global warming, but also has a more immediate effect, owing to widespread reliance on heavy fuel oil (HFO) to power ships.
HFO has been the “king of marine fuels” since the 1960s, but only in recent years has it come under increased scrutiny.
Alternative shipping fuels exist.
The initiative brings together shipping operators, polar explorers, NGOs, communities, and businesses to back an HFO phase-out, ahead of any increase in Arctic shipping, while urging the broader shipping industry to switch to alternative fuels.
Since the commercial development of lithium-ion batteries – the rechargeable batteries common in consumer electronics – in the early 1990s, the challenge of storing and releasing power effectively enough to make sustainable energy sources viable alternatives to fossil fuels has been a vexing one.
The Coming Ice Age in Energy SecurityWorldwide dependence on fossil fuels costs far more than the price of a barrel of crude oil.
With the world economy remaining dependent on fossil fuels well into this century, energy vulnerability will only increase in the foreseeable future.
Renewable energy sources are promising, but they will not soon replace fossil fuels.
While carbon dioxide is a greenhouse gas, natural gas produces less of it than other fossil fuels.
Our dependency on carbon-emitting fuels is more than enormous.
Fossil fuels account for more than four-fifths of the world’s energy diet.
What if, instead of spending trillions of dollars trying to build an impossible number of power plants – or, more likely, condemning billions of people around the world to continued poverty by trying to make carbon-emitting fuels too expensive to use – we devoted ourselves to making green energy cheaper?
Right now, solar panels are so expensive – about 10 times more than fossil fuels in terms of cost per unit of energy output – that only well-heeled, well-meaning (and, usually, well-subsidized) Westerners can afford to install them.
But think where we’d be if we could improve the efficiency of solar cells by a factor of ten – in other words, if we could make them cheaper than fossil fuels.
Forget about subsidizing inefficient technologies or making fossil fuels too expensive to use.
Low-carbon primary energy means three options: renewable energy, including wind, solar, geothermal, hydropower, and biomass; nuclear energy; and carbon capture and sequestration, which means using fossil fuels to create energy, but trapping the CO2 emissions that result and storing the carbon safely underground.
Third, we face steeply rising prices for fossil fuels, as developing countries’ growth drives up demand and conventional supplies of coal, oil, and gas are depleted.
Sure, we can find more fossil fuels, but at much higher cost and at much greater environmental risk from industrial spills, waste products, leaks, and other damage.
Americans are bombarded by industry-funded media downplaying climate change, while countries that are much poorer in fossil fuels are already making the necessary transition to a low-carbon future.
He fuels Israeli fears and disillusionment, in order to preserve a status quo that, at least in the case of Palestine, benefits Israel.
At this critical point, when the fossil fuels that have brought us so much prosperity could lead to our demise, it is again technological innovation that can steer us onto a better path.
Addressing the problem of climate change requires reducing emissions of carbon dioxide from fossil fuels, which in turn involves choices in technology, some of which already exists and much of which needs to be developed.
And, with more maize and soybeans being used for fuels rather than food, the food supply tightens even more.
Another is that the world needs a much more serious cooperative effort to develop long-term environmentally sound technologies to substitute for scarce oil and gas and for fuels produced from farmland.
Ending our reliance on fossil fuels requires a complete transformation of the world’s energy systems.
No alternative form of energy is efficient enough to compete with fossil fuels at scale.
Other than nuclear power – which is still much more expensive than fossil fuels – all of the known possibilities require significant research and development.
