Energy & Electricity in Science : How Is Nuclear Energy Used Today?

Hi I’m Steve Jones and I’m going to tell you how nuclear energy is used today. Basically nuclear energy is very very expensive initially to produce and power stations and so forth are quite large and therefore the uses of nuclear energy have to be on the side of a power station in general. So […]

Energy & Electricity in Science : How Is Solar Energy Used?

Hi I’m Steve Jones and I’m going to tell you some of the uses of solar energy. Now solar energy is one f those strange sources of energy which is very seldom used on its own. The reason for this is that the source of the energy, the sun is not always there and therefore […]

Why Are Leaves Green? Part 1

You’ve probably learned that leaves are green because they’re full of a green molecule called chlorophyll – it’s the reason for the greenness of plants, from moss-green moss to grass-green grass to ever-green evergreens. And the reason chlorophyll is so incredibly popular–showing up in nearly every plant on Earth–is that it’s good at soaking up […]

What If We Covered The Ocean With Solar Panels? | Unveiled

What If We Covered the Ocean with Solar Panels? With the planet’s future at stake, switching to renewable energy has never been more important, and solar power is usually put forward as one of the best options. So far, plans for solar farms have mostly taken shape across sprawling expanses of open land. But the […]

Energy & Electricity in Science : How Heat Can Produce Electricity

Hi I’m Steve Jones and I’m going to explain how heat is going to produce electricity. The first thing we have in this diagram is a boiler and the boiler will produce steam. How can we produce the steam? The answer is we can produce it from things like nuclear energy if we wish, a […]

Energy & Electricity in Science : How Does Solar Energy Work?

Hi, I’m Steve Jones, and I’m going to explain how solar energy works. Now, solar means sun, so we know that the energy is coming from the sun, and we might think it comes as heat or whatever. In fact, we get all kinds of energy from the sun, but it is all radiation. Remember, […]

TRANSPARENT Solar Panels?!

Hi, this is Kate from MinuteEarth. Solar panels pretty much only come in one color: dark. That’s because they use dark sheets of silicon crystals to absorb the sun’s rays, then turn them into electrical energy. And solar panels are becoming so cheap and so efficient that soon, whole cities could run on sunlight…except that […]
