Three fossil fuels — petroleum, natural gas, and coal — have provided more than 80% of total U.S. energy consumption for more than 100 years. In 2015, fossil fuels made up 81.5% of total U.S. energy consumption, the lowest fossil fuel share in the past century. In EIA's Annual Energy Outlook 2016 Reference case projections, which reflect current laws and policies, that percentage declines to 76.6% by 2040. Policy changes or technology breakthroughs that go beyond the trend improvements included in the Reference case could significantly change that projection. moreless

An interview with James Hansen at the American Geophysical Union Fall Meeting. Here, Dr. Hansen speaks in simple, politically astute terms about how best to put a price on carbon. We are already paying a carbon tax, with the lungs, brains, and organs of our citizens, and it is costing us billions. It’s time we face up to consciously pricing fossil fuels so that we can make market based, rational decisions on our energy policy. moreless

Do numbers speak? Here are the numbers, and here are explanations of what they are saying. The truths are more important than the myths. Should be obligatory reading. moreless

This Synthesis Report is based on the assessment carried out by the three Working Groups (WGs) of the Intergovernmental Panel on Climate Change (IPCC). It provides an integrated view of climate change as the final part of the IPCC’s Fourth Assessment Report (AR4). Topic 1 summarizes observed changes in climate and their effects on natural and human systems, regardless of their causes, while Topic 2 assesses the causes of the observed changes. Topic 3 presents projections of future climate change and related impacts under different scenarios. Topic 4 discusses adaptation and mitigation options over the next few decades and their interactions with sustainable development. Excellent example of the thinking and methodology, but not the most recent data. moreless

Shows how, based on Swedish and French deployment data, it would be possible to replace all fossil fuel used for electricity generation by nuclear. moreless

US commitment to COP22. This document lays out a strategy to deeply decarbonize the U.S. economy by 2050. This document has been presented immediately after the US 2016 election results. At this point in time, little is known about the future of these very worthwhile commitments. moreless

J M Jancovici explains why RE is 6x more expensive than nuclear, and 10x more for solar. moreless

A biannual dashboard that reports on the progress of the energy transition plan - sector by sector vs the objectives. This first iteration shows that achievements are already behind objectives, and suggests that economic subsidies are aimed at the wrong targets. moreless

Graph showing most of the climate-related parameters, including the cumulative CO2 (carbon dioxide) emissions by country. Much useful data. Data source was the World Resources Institute. moreless
