With the increasing demand for energy such as oil and gas, people start to look for their sources in remote and untouched places. Do the advantages of this development outweigh the disadvantages? Give reasons for your answer and include any relevant examples from your own knowledge or experience...
More massive stars may end their lives in an explosion known as a supernova, but that is not the likely scenario that awaits our own. 1. Hydrogen-burning phase Every second the Sun converts 600 million tonnes of hydrogen into four million tonnes of energy: the rest is converted into ...
Nuclear fusion is what keeps the Sun and all other stars shining in the sky. The Sun is a glowing ball of mainly hydrogen and plasma, which creates energy when the hydrogen atoms crash into each other and release energetic light and helium as a byproduct...

In 1913, Bohr proposed that electrons exist in discrete orbits based on their energy. When an electron jumps from one orbit to a lower orbit, it gives off energy in the form of a photon. The quantum theory of light -- the idea that light exists as tiny packets, or particles, called ...
It's important to use energy efficiently in space, because resources are limited. Energy can't be wasted on light bulbs that don't maximize their output. In addition, different types of lighting create different levels of heat, and extra heat is something spacecraft must eliminate (researchers...
So, what can you do to save energy and water? –Go on a vampire hunt! Household appliances that are unnecessarily left onstandbyare known as ‘vampire devices‘ as they sneakily suck up lots of electricity! Make sure they’re allturned off at the wall, to stop them wasting power. ...
How Do I Clean My Solar Panels? You can clean solar panels on the roof yourself, but since they’re often perched precariously in steep or hard-to-reach spots on the roof, this can pose a safety issue. They also generate electricity, which can also pose a danger. ...
How do you get people to care about climate change? Simple: Make a blockbuster movie about it, packed full of the biggest stars in Hollywood. At least, that was Adam McKay’s approach. The writer and director of ‘Don’t Look Up’ joins the show this week to discuss the film, which...
