With growing demand and dwindling resources, there's only one direction fuel bills are going. But soon we could have power stations in our gardens

BACKYARD POWER STATIONS

Energy prices are high almost everywhere in the world and are getting higher.

It's turned the cost of the fuel we use to power our homes into a political issue that's changing the course of elections. In the UK, household energy bills have risen by 34 per cent since early 2022. Meanwhile, everyone is trying their best to ignore the elephant in the room - the looming climate crisis.

But there's a point of light on the horizon. Technology is being developed that may release us from this monstrous mess by allowing us to generate our own clean, cheap energy at home. In ten years, many more of us may not only be generating enough power for our own needs, but also selling the excess back to the power companies. It's a win-win-win situation: pollution and emissions are reduced, energy efficiency goes through the roof and homeowners no longer need to worry about whether power company bosses fancy a new boat for Christmas.

The technologies that enable this vision of the future are known as 'microgeneration' because they permit the generation of electricity and heat on far smaller scales than traditional power plants. While a single big plant is often more efficient than thousands of small ones, a significant portion of what it produces is then lost between the power station and your house. But by attaching what is essentially a small power plant to your house, losses are minimised.

The options for homeowners, small businesses and communities to generate their own power are currently fairly limited. Today's generation of solar panels and wind turbines are effective when used en masse, but on a smaller scale they can take upwards of 10 or 20 years for the reduced energy bills to fully offset the upfront cost of installation.

Melting glaciers could trigger volcanic eruptions around the globe

Melting glaciers could make volcanic eruptions more explosive and frequent, worsening climate change in the process, scientists have warned. Hundreds of volcanoes in Antarctica, Russia, New Zealand and North America rest beneath glaciers. But as the planet warms and these ice sheets melt and retreat, these volcanoes are likely to become more active, according to the authors of a new study analysing the activity of six volcanoes in southern Chile during the last ice age. “Glaciers tend to suppress the volume of eruptions from the volcanoes beneath them. But as glaciers retreat due to climate change, our findings suggest these volcanoes go on to erupt more frequently and more explosively,” said Pablo Moreno Yaeger, a graduate student at the University of Wisconsin-Madison.

The world's dams hold so much water they've shifted Earth's poles

The construction of thousands of dams since 1835 has caused Earth's poles to wobble, new research suggests. Scientists found that large dams hold so much water, they redistribute mass around the globe, shifting the position of Earth's crust relative to the mantle, the planet's middle layer. Earth's mantle is gooey, and the crust forms a solid shell that can slide around on top of it. Weight on the crust that causes it to shift relative to the mantle also shifts the location of Earth's poles. \"Any movement of mass within the Earth or on its surface changes the orientation of the rotation axis relative to the crust, a process termed true polar wander,\" researchers wrote in the journal Geophysical Research Letters.
