Wind, solar, and storage could meet 90–100% of America’s electricity needs

In order to combat climate change, we need to rapidly move from fossil fuel energy to clean, renewable energy. The two energy sources I am most interested in are wind and solar power; however, there are other sources that have great potential.

Some people doubt how much wind and solar can supply to a country’s electricity grid. This is a particularly challenging question to answer in part because both solar power and wind power fluctuate in both space and time. We all know solar panels work well during the day, when the sun shines – they don’t work so well at night. And wind turbines only send electrons when the wind is blowing.

Mayor of London and green groups call for swift action after new research suggests government cuts are putting wildlife protections under threat

Sadiq Khan has accused ministers of stalling over the setting up of a new tough environmental watchdog body post Brexit.

The mayor of London spoke out as research by the country’s leading environmental bodies suggested protections to wildlife, water and air quality are under threat because of budget cuts of more than 55% over the last eight years.

Dairy farms need female cows to produce milk but with little demand for male calves many farmers can’t afford to keep them beyond birth

The number of male calves being killed straight after birth is on the rise again, despite efforts by the dairy industry to end the practice known as ‘the dirty secret’.

A Guardian analysis shows that it can cost a farmer up to £30 per calf to sell it on for beef or veal, while early disposal costs just £9. A growing number of farmers feel compelled to take the latter option, with 95,000 killed on-farm in the most recent set of figures.

Carpenter’s Lodge, Lincolnshire: Why was a kestrel so interested in the rising corner of a small rural overpass?

The climbing bend of an overpass, in a frigid easterly wind, early. I’ve come because of an eye-hook bird I’ve often seen hovering here. A kestrel – static in the air as if on a pole, above this corner in precisely the same place. More recently, I’ve seen a red kite showing interest too, wheeling and listing and riding the wind like its namesake. If it was a child’s kite, its line would have been tied to the barrier of this bend.

I’ve seen the kestrel for years, usually at dusk, against the sunset sky like a mad little spatter of dirt on a west-facing window. Wings frantic, head down, tail splayed. Watching.

Artificial islands that are now mushrooming across the ocean are regarded as 'engineering marvels'. But, little attention is paid to how these human-made structures affect sea life.

Gold plated or not, the idea that governments would agree to a write-down or rebate on network costs is laughable.

State governments now have an opportunity to reset the clock – to pay off the mistakes of the past and let consumers guide choices about our future grid.

High spot prices and better than expected output from new Kidston solar farm delivers revenue bonus - but it won't last.

Sawmillers say industry in ‘wind-down mode’ as state government discusses logging agreements extension

Victoria’s national parks and water catchments should be opened up for sustainable logging, according to a group of six Victorian sawmillers.

The sawmillers – who call themselves the G6 – say the Victorian timber industry is in crisis. They want access to either more timber or exit packages.

We may be only a few years from hearing the purring of the last turtle dove in the UK, writes Jonathan Wallace

Thank you Jonathan Franzen (Why do birds matter? Where shall I begin? 24 March) for your wonderful paean to birds. They enrich our lives yet we continue to push birds towards oblivion. We may be only a few years from hearing the purring of the last turtle dove in this country, for example. There are many ways in which we harm bird populations, some easier to address than others. The outrageous persecution of birds of prey on some shooting estates could be stopped tomorrow with sufficient goodwill and government commitment. Slowing the general bleaching of wildlife from our countryside is less straightforward and will require creative thinking in order to balance the legitimate need for farmers to make a living and produce food with the need to protect wildlife, water supplies and soils. We must not shirk the challenge or Mr Franzen’s grandchildren will be denied the opportunity of experiencing anything but a fraction of the wonders he has enjoyed.
