Why Wind Farms Can Be Relied On For Almost Zero Power

November 17, 2014 by Robert Wilson
155

Wind Farms and Back Up

A common claim about wind farms is that every unit of installed wind capacity needs to be backed up by one unit of fossil fuel capacity. Some claim that wind farms do not reduce carbon emissions; while others tell us that wind farms do not need much back up in the first place. Both assertions are demonstrably false.[read more]

How Solar PV Can Power A Carbon-Free Energy Revolution, In Four Charts

Solar PV and Carbon Reduction

Can we build enough carbon-free energy, and can we do it fast enough, to avert the catastrophic effects of climate change without having to power this energy transition with fossil fuels that would undermine the whole transition? The answer is “yes.”[read more]

Is Renewable Energy Less Effective Than Energy Efficiency at Reducing CO2 Emissions?

October 29, 2014 by Willem Post

The policies to implement worldwide renewable energy build-outs are, as of yet, far from sufficient to reduce global CO2 emissions. At the same time, I believe these policies are yielding significant adverse results regarding economic competitiveness.[read more]

European Nations are Increasing Electricity Generation Using No-Carbon Sources

European Energy Generation

Penetration rates of no-carbon generation have increased from 50% to 56% in recent years in Europe. Increasing levels of renewable generation, along with nuclear generation, mean that many European countries generate a large share of their electricity from no-carbon sources.[read more]

Research your Intensity: Why Carbon Intensity of Your Electricity is Important

August 3, 2014 by Lindsay Wilson

Carbon Intensity and Electricity

To live a really good low-carbon-emissions-producing life you’ll need plenty of low-carbon electricity. But how carbon intensive your electricity is at the moment is what ends up dictating the benefits of things like going solar or getting an electric car.[read more]

Cap-and-Trade's Moment of Truth

Cap, Trade, Truth

With the looming expansion of its cap-and-trade program to transportation fuels like gasoline, California is fast approaching a significant moment of truth for its climate policy. This has some people nervous, and there are growing rumblings of proposals to delay the expansion of the cap to transportation fuels.[read more]

For Some Utility Execs, EPA Carbon Rules Are Only One Worry in a Changing Business

June 9, 2014 by Martin LaMonica

One would think that the recent landmark EPA proposal to limit CO2 emissions from power plants would be the main topic of discussion at a utility industry conference. But that wasn't the case at this week's Utility of the Future conference in Washington, D.C.[read more]

Shale Gas: Killing Coal Without Killing CO2

Shale Gas and CO2

CO2 Scorecard has been conducting detailed analysis on the environmental implications of the newfound popularity of natural gas. In May 2013 we demonstrated that only 25% of US emissions reductions were attributable to the switch from coal to natural gas in 2012.[read more]

Is There Cause for Optimism on Emissions?

Emissions Optimism?

Perhaps the BBC and others are having a bit of a fit of pre-COP optimism, but two recent stories would lead the reader and/or listener to the view that the world is, perhaps, at last turning the corner on the reduction of emissions.[read more]

How Much Is Efficiency Helping America Slash Its Carbon Emissions?

Carbon Emissions Efficiency

Energy wonks collectively gasped when the Energy Information Administration closed its doors briefly during the recent government shutdown. But the agency opened back up with a bang this week, issuing a promising new report that showed continued declines in America's carbon intensity.[read more]

New Study: Carbon Reduction Opportunities for Oil Industry Are Significant

Carbon Reduction and the Oil Industry

While the substitution of cleaner energy sources for crude oil, like advanced renewable fuels made from agricultural waste, is a key strategy to reduce carbon pollution, it is also important to employ technologies that can directly reduce the pollution generated from crude oil extraction and refining.[read more]

Energy Truth: Solar Reduces Emissions Despite Variability

Solar Energy Emissions Reduction

As a researcher, I’d like to come right out and thank the coal industry for creating a never-ending stream of research opportunities. You’re awesome. Like a constant conveyor belt of coal, they seem to be able to roll out a never-ending stream of myths and challenges.[read more]
