Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.

A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.
The coming year will reveal if the country is serious about developing its wind energy.
Renewable energy is expanding at a record pace, but still not fast enough. Here are the key areas to watch for progress in bringing more wind and solar into the power grid in 2022.
Millions of years of on-off ice ages have left behind a mix of different sediments.
The Biden administration is proposing a big increase in offshore wind power. A former state official explains how regulators find the best sites and balance competing interests.
More than ten offshore wind farms are currently proposed for Australia. If built, their combined capacity would be greater than all coal-fired power plants in the nation.
Carbon emissions from maritime shipping and port activities are on the rise. But city ports are finding ways to reduce their carbon footprints and reconnect with nearby cities.
Rather than considering the job done, Tasmania should seize opportunities including renewable energy, net-zero industrial exports and forest preservation.
None of Australia’s highest-emitting energy firms are fully or even closely aligned with global climate goals. Just one goes even partway, and five appeared to be taking no action at all.
The Biden administration has a goal of getting from today’s 42 megawatts of offshore wind power to nearly 30,000 by the end of the decade, but there are still obstacles ahead.
Despite a growth in revenue from wind farms, many rural school districts are being nudged by policy and law to spend the money on buildings and not instruction.
Right now, the nation is almost entirely dependent on other countries for minerals that are used in everything from wind turbines to strike fighters and satellites.
To increase renewable energy use, the Biden administration wants the US to go from seven offshore wind turbines today to enough to power 10 million homes within a decade.
Wind turbines in cold areas typically include methods for removing and repelling ice, but those methods can waste energy. There’s a better way.
The transition to 100% renewable energy will require a lot of land – mostly in regional Australia. This presents big challenges, and opportunities, for the farming sector.
Last year, renewables provided a whopping 60% of South Australia’s electricity supplies. The remarkable progress came as national climate policy was gripped by paralysis – so how did it happen?
Ramping up fossil power sources is no longer a good option in an energy-supply crisis. Bring in the weather forecasters.
The latest estimates of electricity generation costs in Australia find renewables will soon be the cheapest even with grid integration expenses.
Ever wanted to own your own wind farm? Well now you can.
