Fossil Fuels vs. Renewables: A Price on Reliability?

Union of Concerned Scientists

The same scenario has played out with the power plants that use fossil fuels, predominantly methane (“natural”) gas, delivered by pipelines. The electric power system is trapped by gas-dependent power plants that cannot obtain gas when it needs it to keep the lights on. It’s a vicious feedback loop.

How Are Lithium-ion Batteries that Store Solar and Wind Power Made?

Union of Concerned Scientists

Batteries can also be used to assist with peak electricity demand; currently instead of batteries, fossil fuel-powered “peaker plants” are often used to supply energy during high-demand periods. Where do their raw materials come from, and how can we ensure their valuable contents are recovered rather than wasted?

Illinois Has No Time to Waste in Building Its Carbon-Free Electricity Future

Union of Concerned Scientists

By combining these supportive policies with studies of where they can be most effective in supporting the power grid, Illinois can see where to best focus its clean energy development efforts. This “heat map” displays the results of power flow modeling with Illinois PJM-connected coal and gas plants removed from the system.

Wind-powered Cargo Vessel Holds Hope for a Greener Future

Ocean Conservancy

While a wind-powered cargo vessel may seem like a 19 th Century idea, the Grain de Sail may be a herald of a greener future rather than a nostalgic nod to the past. By the end of the week one thing seemed likely, a price on shipping fuel’s carbon emissions even if it doesn’t end up being the exact levy proposed by the Marshall Islands.

Challenges and Opportunities in Mining Materials for Energy Storage Lithium-ion Batteries

Union of Concerned Scientists

Generating and storing clean energy is a lifeline for the planet’s future; burning coal, oil, and gas fossil fuels causes 75% of greenhouse gas emissions. A fossil fuel energy grid extracts and expends finite resources. It is wasteful by design. How are Lithium-ion Batteries that Store Solar and Wind Power Made?

Opinion: What the gas crisis tells us

A Greener Life

This is a signal not only of the country’s unhealthy reliance on fossil fuels but also a failure to move away from gas in a way that other countries have done successfully. Now such a crisis has arisen again. UK’s hugely inefficient housing stock means most homes and buildings do a very poor job of conserving heat.

Analysis: Is hydrogen the new oil?

A Greener Life

The 2020 Tokyo Olympics will be powered by hydrogen. Hydrogen may have lost the race to fuel electric cars but it looks a likely contender to replace fossil fuels in trucks, ships, planes and heavy industry. The Tokyo Olympics will be powered by a fuel with ambition – hydrogen. By Fred Pearce.
