Replacing fossil fuel-reliant power stations with renewable energy sources, such as wind and solar, is a vital part of stabilising climate change and achieving net zero carbon emissions. Professor Magda Titirici, Chair in Sustainable Energy Materials at Imperial College London, offers an introduction to renewable energy and the future of clean, green power in the UK. What is renewable energy?
Energy drinks often contain high amounts of added sugar and caffeine. The Food and Drug Administration (FDA) advises that a healthy adult can usually consume 400 milligrams (mg) of caffeine per day without experiencing any negative or dangerous side effects. However, some people may be more sensitive to the effects of caffeine than others. Manufacturers
You probably remember your grade school science teachers explaining that energy can neither be created nor destroyed. That’s a fundamental property of the universe. Energy can be transformed, however. When the Sun’s rays reach Earth, they are transformed into random motions of molecules that you feel as heat. At the same time, Earth and the
Around 4.6 billion people use the internet every day. In fact, 350,000 tweets have been sent in the past minute. We tend to think of the internet as something ephemeral – partly thanks to terms like “web” and “cloud” – but the servers that host all that data produce huge amounts of emissions, leaving giant
Meet Geothermal power, Geo for short. He’s not really at home in Scotland. He’s an extreme kind of guy. He likes a bit of danger. He’s happiest in places with earthquakes and volcanos – where tectonic plates meet. Tectonic plates are giant slabs of solid rock that make up the Earth’s crust. The plates sit
OK, then, what’s not great about fossil fuels? Hopefully, you already know the answer to this question. When you burn a fossil fuel, you produce carbon dioxide. Carbon dioxide is a greenhouse gas, and it contributes to climate change. If we keep burning fossil fuels, the increase in carbon dioxide is going to change the
Energy drinks are popular beverages meant to improve energy, alertness, and concentration. They contain ingredients that aim to boost these mental and physical aspects, such as caffeine, sugar, B vitamins, herbal extracts, and amino acid derivatives like L-taurine. While they can deliver benefits, energy drinks have a number of associated health concerns related to excessive

The world cannot avoid dangerous climate change without moving to “near zero emissions” before the end of the century, according to the Intergovernmental Panel on Climate Change. Zero-carbon sources of energy will be key to this transition and in the power sector they are already being added more quickly than fossil fuels. So just how
