A mapping service allowing visual comparison of renewable energy statistics in Europe is now available from the specialist search engine for renewable energy and energy efficiency, reegle. Users can select renewable energy statistics in European countries and compare them using a time lapse animation on a full-screen map with the underlying data provided by Eurostat. Energy data is available back to 1997, so users can digest trends over time and compare how different European countries have moved forward on clean and renewable energy over the selected period.

LONDON, United Kingdom — Ranking the oil and gas industry on sustainability may be an endeavor prone to oxymorons, but a new report from Two Tomorrows has attempted just that, scoring the 10 largest fossil fuel companies on five categories of leadership. The results show an industry that is by and large embracing innovation, but falling short on a number of other mission-critical areas, notably peak oil and climate change.

Demand for oil in developed nations peaked in 2005, and changing demographics and improved motor-vehicle efficiency guarantee that it won't hit those heights again, IHS Cambridge Energy Research Associates says in a new report. Reduced petroleum demand in developed nations could make their economic growth less vulnerable to oil price shocks, the report states. Nonetheless, global oil demand is still expected to grow, overall, driven by China and other developing nations as the world economy recovers.

Ever wonder how much space we would need to use to power the entire world with solar energy or offshore wind power? So did the good people at the Land Art Generator, who created two infographics that show the amount of surface area required to power our planet with renewable resources. According to Land Art Generator, 496,905 square kilometers are needed to power the world with solar energy. That's less than the surface area of Spain. And just a piece of the Sahara Desert could power all of Europe and North Africa.
