Think of it as a worldwide addiction. At least 80 percent of the energy people use to drive, heat their homes, and power their gadgets comes from fossil fuels such as coal, oil, and natural gas, and the consumption of all of the above contributes to global warming.
Kicking that addiction will be hard. Cutler Cleveland, a College of Arts & Sciences professor of earth and environment and director of the Center for Energy & Environmental Studies, says the transition from fossil fuels to low-carbon alternatives like wind, solar, and nuclear power will require speedy technological advancement, huge capital investments, and the political—and personal—will of ordinary people. Cleveland, who has written or edited six books on ecological economics and energy transitions and is the founding editor in chief of the online reference source Encyclopedia of Earth, is convinced that to “avert the more dire scenarios, there needs to be radical surgery now.”
Cleveland’s convictions come not only from his own research, but also from a series of eight seminars that brought environmental experts from universities in the United States and Europe to BU during the 2010–2011 academic year. The John E. Sawyer Seminars on Energy and Society were sponsored by the University’s Frederick S. Pardee Center for the Study of the Longer-Range Future and supported by a grant from the Andrew W. Mellon Foundation. “We will have to engineer the transition,” he says. “And we’ve never really done that in the history of humanity.”
Still, he sees encouraging growth in some sectors. Government subsidies and technological improvements in the manufacture of turbines have lowered the cost of wind energy, so that it now competes with energy produced by natural gas and coal. But solar, which has also benefited from subsidies and technological advancements, and wind account for only a couple of percentage points of total power generation in the world.
Nuclear power, another low-carbon energy source, currently provides 3 percent of the world’s energy, Cleveland says, but its hazardous waste disposal and safety risks make it less desirable than wind and solar.
And biomass—such as switchgrass, corn, or sugarcane converted to biofuel—is another alternative source of energy, but Cleveland is discouraged by the carbon exchange of the biomass process.
“When you compare the energy in the ethanol and all the energy it took” to plant, cultivate, transport, and process it, “it’s only a very modest win,” he says. “It’s certainly way less than the energy gain you get from just producing oil directly from crude.”
What does his research tell him about the best way to break the fossil fuel habit? The first step should be using fossil fuels to build a sustainable energy infrastructure. “You need to shift away from coal and oil to natural gas in the short run, and probably leave a lot of coal in the Earth’s crust,” he says. “And you need to use fossil fuel to radically ramp up renewables and/or nuclear.”
That means “sticks and carrots, a lot of them,” he says. “If you want the transition to happen faster than it otherwise would, you’re going to have to alter incentives. And you’re going to have to change the price of carbon.”
Gas tax hikes, like the one Massachusetts Governor Deval Patrick recently proposed, or divestment from fossil fuels are moves in the right direction. Cleveland thinks federal legislation taxing carbon or an international cap-and-trade system would put a bigger dent in emissions.
Finally, he says, politicians have to address the “third rail of US energy policy”—demand. People need to know that their choices can have a negative impact on the environment. “Working 30 miles from home and driving a Hummer to work alone in the morning is probably one of the most absurd, extravagant behaviors,” he says. “We’ll look back and say, ‘Oh my God!’ The excesses of the Romans will look like Romper Room.”
Good work, Cutler. Really a good article about global warming. It will create great awareness among common people. Thanks for sharing.
It’s mind blowing to me that many people still think global warming in a hoax…
Nice work. A really good article about global warming. Thank You for sharing this.
Energy causes things to happen around us. Look out the window.
During the day, the sun gives out light and heat energy. At night, street lamps use electrical energy to light our way.
When a car drives by, it is being powered by gasoline, a type of stored energy.
good article, hopefully remind everyone about the dangers of global warming
In South East Asia, El Nino is typically associated with drought.
Global warming is a serious issue for the survival of mankind on this earth, so we should make a sincere effort to shift toward an ecofriendly lifestyle.
Tax rebates are the thing. How has Switzerland made the move to wind energy, my friend? TAX REBATES.
The incentivization for moving to alternate energies is not in proper shape. The inclination for authorities to kick in an incentive structure is there, but ground level sensitization and education modes are still not in place. Till the time, execution is not at par with ideas, it will never move forward.
Totally agree with you, Saving energy is very critical issue now.
I agree with you, if we save a lot of energy, we will also be able to save the world .
security and good of the world is on ourselves
I wonder how falling energy prices will affect all this? With oil being so cheap now, it might be a fair to question how much global warming will continue to be an issue?

In South East Asia, El Nino is typically associated with drought. The worst on record in Indonesia in 2015, according to the World Meteorological Organization (WMO). The Mekong delta also is facing a historic dry period.
I agree with this. Due to the energy saving means that the earth will be saved
thanks great post, why not change to another alternative energy?
This time we must be conscious to switch from using fossil energy to renewable energy future for our children . wind energy , light , geothermal should be empowered for the good of man
i think global warming is dangerous both humans and plants. switching to non-global warming energy is the best idea.
Going the natural gas route is
proving to be very dangerous
with shale fracking. Once we can
empower the individual to build
his own energy sources, that will
tilt the scales. My brother drives
a Volt and powers it with solar
he has installed on his garage
roof. He basically drives cost
and carbon free.
I think the reason many people don’t see Global warming happening is because it’s a gradual process. Most of us won’t even live long enough to see any significant change in our environment but future generations will. I think it’s a bit selfish to think that because global warming isn’t happening, then we should continue destroying the environment.
I honestly don’t really see global warming as that big of an issue. It’s been talked about for years, but I don’t personally see reports or anything getting worse. Perhaps it is, but really slowly.
Regardless, I’ll probably be dead, and so will my children, before this causes a major problem, in my opinion.
Great article, it is important to think about every decision we make with respect to our energy footprint, and how that effects the environment. I am a big fan of using all LED lights in my house, and I drive a Prius. These are very small changes that I have made, but I believe they have a lasting impact.
I read an article from geologist research and what they said make me affraid, on their research is about “what happen to the wordl if we burn all fosil oil?” and you know what the result? extrem global warming and so many cities will sink on to water. This is makes me so panic. I agree to your article that we must to change our habit using fosil oil now before too late. Thank you
Why are we not shifting to other forms of energy? One of energy alone won’t save us from global warming. We need to diversify our energy resources with water, wind, solar, etc.
As a graduate of Physics and law, I would suggest that proper education and awareness towards people about global warming is an essential factor for people to consider eco friendly energy sources.

There is no doubt that some of the increase in greenhouse gases, specifically CO2, is associated with human activity, and therefore it is advisable to take steps to reduce the amount of the principles of sustainable development, primarily cease of extensive deforestation, particularly in tropical regions. Just as it is reasonable to take up and pursue appropriate adaptation measures that will mitigate the effects of the current trend of thermal insulation.

Great article. Read somewhere by 2100 the weather will increase by 2 degrees.

I came to Boston about 12 years ago, and the whole city was a building site. I think they ware creating some kind of underground transport system. Anyway, loved the city and really looking forward to returning.
