Carbon and De-carbonization

Extrapolating Deployment Trends for Solar PV

March 30, 2015 by Adam Whitmore

Solar Trends and the Future

Simple extrapolation of present trends implies around 1800 GW of installed solar PV capacity by 2030, with even faster growth looking possible. Low carbon technologies getting to scale like this, and reducing costs in the process, will help lower the political barriers to increased decarbonization.[read more]

Power Plant Owners can Reduce Emissions with Energy Efficiency: Here's How

March 29, 2015 by NRDC Switchboard

When the Environmental Protection Agency proposed carbon pollution targets for fossil fuel-fired power plants under the Clean Power Plan last summer, the agency recognized that energy efficiency is a powerful tool for reducing emissions in the electricity sector.[read more]

Plant Closure Opportunity: Hitting Those Clean Energy Notes

Plant Closure and Green Policies

It may seem logical that once a power plant closes, another one needs to be built to replace it – after all, we need to make up for its potential energy generation with more natural gas or nuclear-powered energy, right? Maybe, but plant closures are also an opportunity for clean energy.[read more]

The Climate Case for Hydrogen

Climate Change and Hydrogen

When hydrogen is produced with heat pipe OTEC and supergreen electrolysis it can be a silver bullet and fuel-cell advocates would do themselves a very great service by helping in the promotion and facilitation of these two synergistic technologies.[read more]

Carbon Pollution Standards that Begin by 2020: Vital for Climate Security, Human Health

March 26, 2015 by EDF Energy Exchange

Carbon Pollution Standards

The EPA is working on the Clean Power Plan – the first national carbon pollution standards for power plants. It is critical that EPA finalize carbon pollution standards for the power sector that include protective, well-designed standards beginning in 2020.[read more]

Obama Administration Quietly Seeks Extra Boost for Small Modular Nuclear Reactors

March 26, 2015 by Stephen Lacey

Last week, the president issued an executive order mandating a 40% cut in carbon dioxide emissions across government agencies. Buried in the list of qualifying clean energy technologies was a reference to small modular nuclear technologies that are smaller and less capital-intensive than light water reactors.[read more]

Springing Eternal: Seven Reasons for Hope on Climate Change

Hope on Climate Change

Let’s look at what’s been happening in climate change action lately, because after years of bitter disappointment, things look different now. Because after years and years of cynicism, I see elements of a sea change in urgency and attitude on climate.[read more]

Could India's Coal Plans Derail the Global Climate?

March 26, 2015 by Tobias Engelmeier

India Energy Needs and Coal

If India grew its electricity system based on coal (as China has done), would it derail the global climate? Under a “coal-heavy” scenario, India would need to increase is coal-fired power generation capacity from the 156 GW in early 2015 to 677 GW in 2035. What would be the CO2 implications of such a strategy?[read more]

Carbon-as-a-Service Businesses?

March 25, 2015 by Noah Deich

Cleantech Business Development

The Cleantech Group’s annual San Francisco Forum wrapped up earlier this week. The event’s theme was “Cleantech-as-a-service,” and featured parallel tracks named “Cloud” and “Connect.” Overall, this focus on technology-enabled business model innovation shows how mature the cleantech field has become.[read more]

The Emergence and Importance of President Obama's Climate Policy

March 25, 2015 by Steven Cohen

President Obama recently signed an executive order directing federal agencies over the next decade to cut their emissions by an average of 40 percent compared with their levels when he won office in 2008, and to increase their use of electricity from renewable sources by 30 percent.[read more]

Obama Signs Order to Cut Government GHG Emissions and Boost Renewable Energy

March 24, 2015 by Jared Anderson

Obama Administration and Emissions Reduction

Recently President Obama singed an executive order regarding government energy targets, toured a solar panel installation on the Department of Energy’s roof, and gave brief remarks before kicking off a roundtable with large US companies that do over $1 billion in business with the federal government.[read more]

China's Power System: The Green and the Black

March 24, 2015 by Armond Cohen

China Energy Needs and Sources

If you follow energy discussions, you will often hear one of two visions of China’s energy system emphatically described by various pundits and advocates. At first blush, the two visions seem fundamentally in conflict. Only one must be true! How can China be both “green” and “black” at the same time?[read more]

Hong Kong Once Again Leading the Way in the Fight to Control Shipping Emissions

March 24, 2015 by Barbara Finamore

Hong Kong and Shipping Emissions

Hong Kong has just taken another giant step towards controlling marine emissions, the major source of its domestic air pollution. The Hong Kong Legislative Council has just approved a new rule mandating that Ocean-Going Vessels (OGVs) switch to clean fuel while at berth.[read more]

The 100% Renewable Energy Nuclear Option, Part 1

March 23, 2015 by David Hess

Renewables and Future Energy Options

 

It is time for the world to get serious about renewables, by formally recognizing that nuclear energy is one in all ways that matter. Usually the term renewables is taken to mean wind and solar, but this makes the idea of a life and death contest with nuclear all the more ridiculous.[read more]

Is it Time to Broaden the Scope of the U.S. Renewable Fuel Standard?

March 23, 2015 by Daniel Posen

Changing the Renewable Fuel Standard

The Energy Independence and Security Act of 2007 requires refiners, blenders and importers of transport fuels to meet targets that increase progressively through 2022. Seven years later, and the standard is facing two seemingly opposite stumbling blocks: weak supply (of cellulosic biofuel), and weak demand.[read more]
