In-depth: The Whole System Costs of Renewables

Dramatic cost reductions mean wind and solar can now compete on price with conventional sources of energy in many parts of the world, including the UK. This turns the spotlight onto the so-called “whole system costs” of integrating renewables into the electricity system, which include backing up intermittent generation and strengthening grids.

Battery Power Boost to Renewables

Researchers at the John A Paulson School of Engineering and Applied Sciences at Harvard University in the US say in an article published in ACS Energy Letters that they have now developed a long-lasting flow battery capable of storing renewable power that­ could operate for up to 10 years, with minimum maintenance required.

Renewable Electricity Generation In Asia – A Realistic Assessment

The situation in Asia shows the problem facing the global electricity sector; as rich countries struggle to peak or reduce emissions, newly industrializing countries are rapidly increasing fossil fuel usage as they move through the energy intensive early stages of industrialization.

Renewable Electricity Generation In Western Europe & Scandinavia – A Realistic Assessment

Western Europe and Scandinavia have been held up as leaders in moving to a low-carbon future in electricity generation, but the reality is very mixed. Scandinavia benefits from its large hydroelectric resources, relative to population size, and therefore has a very low electricity carbon footprint. France is low carbon due to its predominantly nuclear-based generating capacity.

Four Strong Winds: First US Offshore Wind Project Launches

As the public learned of the recent opening of America’s first offshore wind power project, many wondered why it took so long? This week on Sea Change Radio, we talk with the executive editor of EcoRI News, Tim Faulkner, to discuss the opening of the Block Island Wind Farm off of Rhode Island.

How to Make Hydropower More Environmentally Friendly

NOTE: Images in this archived article have been removed. Hydropower provides 85 percent of the world’s renewable electricity, but comes with a hefty environmental price tag. Here’s what some are doing to fix that. December 20, 2016 — Humanity got its first large-scale electricity thanks to hydropower. On Aug. 26, 1895, water flowing over Niagara … Read more
