Launching our Power Sector Carbon Index!

Today we are launching our Power Sector Carbon Index! Check it out at https://emissionsindex.org!

The Power Sector Carbon Index provides an estimate of the carbon dioxide (CO2) intensity of the U.S. power sector using publicly available data sources. Carbon intensity is measured in pounds of CO2 per Megawatt-hour (MWh) of electricity.

What is the carbon intensity? See below!

ZERO EMISSIONS DAY: CHINA’S WIND ENERGY INFRASTRUCTURE

From the article:

“In December 2015, U.S. President Barack Obama and Chinese President Xi Jinping attended the United Nations’ 21st Climate Change Conference (UN COP21). The two presidents, representatives of the two largest producers of greenhouse gases on the globe, pledged to work together to establish a climate change agreement to mitigate the enormous impact greenhouse gases have had, and are having, on global warming.

“Thus, the Paris Agreement was formed. This agreement, the world’s first comprehensive climate agreement, is a pledge negotiated by the 196 countries in attendance at UN COP21 to reduce global greenhouse gas emissions by adopting renewable energy sources.

“In the wake of the Paris summit, engineering and public policy (EPP) Ph.D. student Long Lam studies China’s efforts to deploy renewable energy and mitigate its carbon emissions. Focusing on wind and solar energy, Lam studies China’s wind turbine innovation capabilities, dynamics within the solar photovoltaic industry, and the trajectories of various solar photovoltaic technologies in the marketplace.

“Lam recently published a paper, co-authored by EPP Associate Professor Inês Azevedo and Social and Decision Sciences’ Lee Branstetter, entitled “China’s wind electricity and cost of carbon mitigation are more expensive than anticipated.” The paper, published in Environmental Research Letters, discusses how China’s efforts to cut emissions from its coal power plants by 60% by 2020 have been slowed, despite a massive initiative to build up the country’s wind energy infrastructure.”

Lawrence Berkeley National Laboratory, in collaboration with experts at Stanford, Carnegie Mellon, and Northwestern, today released our latest analysis of electricity used by data centers in the US. Surprisingly, electricity use in data centers has been roughly flat since the financial crisis with little growth projected to 2020, even though delivery of computing services has been increasing rapidly. As I’ve argued for years, the level of inefficiency in enterprise data center facilities leaves lots of room for improvement, and the market is finally getting that message.
