Offshore wind farms solve one of renewable energy’s biggest problems: unreliability. With wind almost always blowing on sea, there is no lack of power. But the technology is struggling with a bunch of other hurdles.

We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.

5 types of Renewable Energy including solar,wind,ocean,hydroelectric and geothermal energy.

Science Standard: S6E6 a. Ask questions to determine the differences between renewable/sustainable energy resources (examples: hydro, solar, wind, geothermal, tidal, biomass) and nonrenewable energyresources and how they are used in our everyday lives.

Harnessing the power of the highest tides in the world produced by Canada’s Bay of Fundy has been a major engineering challenge. Sustainable Marine just did it, and they’re now selling tidal energy to the Nova Scotia government. The Weather Network was invited out to tour the floating platform to get a first hand look at the next gen technology just off Westport, Nova Scotia.

Script:
Renewable energy resources are being developed because we are running out of fossil fuels at an exponential rate.

The wind is produced as a result of giant convection currents in the Earth’s atmosphere, which are driven by heat energy from the sun. Wind turbines use the wind to drive turbines directly. The blades are connected to a housing, which contains gears linked to a generator. As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator. The advantages are that there are no fuel costs and no harmful pollutant gases are produced. However, they depend on wind, if there is no wind, there’s no electricity.

Like the wind, water can be used to drive turbines directly. Wave machines use the kinetic energy in this movement to drive electricity generators. Another way of using the water is to build a tidal barrage over a river estuary to make use of the kinetic energy in the moving water. The barrage contains electricity generators, which are driven by the water rushing through tubes in the barrage. Hydroelectric power stations are dams built across a river valley. The water high up behind the dam contains gravitational potential energy. This is transferred to kinetic energy as the water rushes down through tubes inside the dam. The moving water drives electrical generators, which may be built inside the dam. Water produced energy is good because no harmful polluting gases are produced and tidal barrages and hydroelectric power stations are very reliable and can be easily switched on. However, tidal barrages destroy the habitat of estuary species and hydroelectricity dams flood farmland and push people from their homes.

Script:
Fossil fuels are non-renewable energy resources; these are coal, oil and natural gas. They were formed from the remains of living organisms millions of years ago and they release heat energy when they are burned. This heat is used to turn water into steam, which is used to turn a turbine, which then drives a generator to generate electricity. There are downsides however, fossil fuels release sulphur dioxide and carbon dioxide which lead to acid rain and an increase in global warming.

Another form of non-renewable energy is Nuclear. The main nuclear fuels are uranium and plutonium. The nuclei of these large atoms are split in a process called nuclear fission to release a great deal of heat. The heat energy is again used to boil water. The kinetic energy in the expanding steam spins turbines, which then drive generators to produce electricity. Unlike fossil fuels, nuclear fuels do not produce carbon or sulphur dioxide. However, they do have the risk of a fault where large amounts of radioactive material could be released into the environment such as the disaster of Chernobyl in 1986.

Solar panels and wind turbines are great, so long as the sun shines and the wind blows. But what if they do not? Well, then we store the energy. But how? In this video I explain how high the risk of a cold, dark, and windless period is — the “cold Dunkelflaute”, and what energy storage we need for intermittent renewables.
