Global Priorities for Zero-Emission Energy Innovation

An expert elicitation and discussion

Tuesday, April 12, 2016

To accelerate affordable, zero-emission energy at global scale, additional funds for research and development (R&D) should be allocated across a broad portfolio, according to a Near Zero expert elicitation—with experts on average allocating more than half the funds toward electricity generation and storage (35% of the total) and transportation (25% of the total).

The effect of natural gas supply on U.S. renewable energy and CO2 emissions

Wednesday, September 24, 2014

The increased use of natural gas for electricity would do little to reduce U.S. greenhouse gas emissions, according to this study, which combines energy modeling and a Near Zero expert elicitation of U.S. natural gas supply. This is primarily because abundant gas delays deployment of renewable electricity.

Keystone XL: The Climate Impact

An Expert Elicitation

Tuesday, September 16, 2014

Survey on how the proposed Keystone XL pipeline would affect future oil sands production and greenhouse gas emissions. Results suggest the pipeline would likely increase emissions, even if the production from KXL replaced an equivalent amount of heavy crude oils, or was transported by rail instead.

The Future of PHEVs

Expert Perspectives on Plug-in Hybrid Electric Vehicles

Monday, June 21, 2010

In preparation for a hearing of the U.S. Senate Energy & Natural Resources Committee, Near Zero invited 60 experts on plug-in hybrid electric vehicles to answer 5 questions on the future cost and environmental benefit of PHEVs.

19 experts participated in this discussion.

Near Zero produces scientific assessments of energy and climate issues. Near Zero projects use innovative online tools to engage experts on the best opportunities for progress toward near-zero emissions, based on scientific data and expert judgment.

Credible, impartial, and actionable information based on scientific data and expert judgment.

A guiding principle is to reveal where experts agree and disagree and why, highlighting areas of consensus and controversy rather than advocating any one perspective. Near Zero integrates this expert knowledge with quantitative modeling and analysis to demonstrate the implications of different views and potential choices. The result is a dynamic digital cache of credible, impartial, and actionable information to support policy and investment decisions.
