Ronald Stein is a Pulitzer Prize-nominated author, internationally-published columnist, energy consultant, engineer, and policy advisor for the Heartland Institute. His books include “Clean Energy Exploitations,” “Just Green Electricity,” and “Energy Made Easy.” He talks to Larry Elder about how people in developing countries are being exploited for the raw materials to make “green energy” products, and they also discuss many of the other shortcomings of the green energy movement.
Big batteries are perhaps the key to making a completely renewably powered grid possible. Luckily there are already some massive ones paving the way. This week Imogen visited Europe’s largest battery energy storage system, Pillswood in Hull to find out how Harmony Energy is getting as much clean energy from Dogger Bank, the world’s biggest wind farm, onshore and into our homes. But these are no ordinary batteries, at 200 MWh these Tesla Megapacks are decked out with Artificial Intelligence, these are working to make the grid both renewable and flexible.

Solar energy is derived by capturing radiant energy from sunlight and converting it into heat, electricity, or hot water.
With the technology to harvest it, there is a limitless supply of solar energy, meaning it could render fossil fuels obsolete.
Wind
Wind farms capture the energy of wind flow by using turbines and converting it into electricity.
Wind energy is a clean energy source, which means that it doesn’t pollute the air like other forms of energy.
Wind energy doesn’t produce carbon dioxide, or release any harmful products that can cause environmental degradation or negatively affect human health like smog, acid rain, or other heat-trapping gases.
Hydroelectric
Water flows through the dam’s turbines to produce electricity, known as pumped-storage hydropower.
Hydroelectric power is very versatile and can be generated using both large scale projects, like the Hoover Dam, and small scale projects like underwater turbines and lower dams on small rivers and streams.
Geothermal
Geothermal heat is heat that is trapped beneath the earth’s crust from the formation of the Earth 4.5 billion years ago and from radioactive decay.
Geothermal energy is not as common as other types of renewable energy sources, but it has a significant potential for energy supply.
Geothermal energy is naturally replenished and therefore does not run a risk of depleting (on a human timescale).
Ocean
The ocean can produce two types of energy: thermal and mechanical.
Ocean thermal energy relies on warm water surface temperatures to generate energy through a variety of different systems.
Ocean mechanical energy uses the ebbs and flows of the tides to generate energy, which is created by the earth’s rotation and gravity from the moon.
Unlike other forms of renewable energy, wave energy is predictable and it’s easy to estimate the amount of energy that will be produced.
This type of renewable energy is also abundant, the most populated cities tend to be near oceans and harbors, making it easier to harness this energy for the local population.
Hydrogen
Hydrogen needs to be combined with other elements, such as oxygen to make water as it does not occur naturally as a gas on its own.
When hydrogen is separated from another element it can be used for both fuel and electricity.
Hydrogen can be used as a clean burning fuel, which leads to less pollution and a cleaner environment.
It can also be used for fuel cells which are similar to batteries and can be used for powering an electric motor.
Biomass
Bioenergy is a renewable energy derived from biomass.
Biomass is organic matter that comes from recently living plants and organisms.
The use of biomass in energy production creates carbon dioxide that is put into the air, but the regeneration of plants consumes the same amount of carbon dioxide, which is said to create a balanced atmosphere.
Biomass can be used in a number of different ways in our daily lives, not only for personal use, but businesses as well.
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.

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.

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.

Hydro Tasmania is Australia’s largest clean energy provider and the largest provider of renewable energy in Australia.
Do you know how we generate electricity from water? This is sometimes referred to as hydroelectricity or hydropower.
It’s all about utilising the two forms of energy that water contains, potential and kinetic, and transferring it into electrical energy.
Potential energy, also known as stored energy, is gained by the construction of dams in varying design along natural waterways.
The water is captured both directly from rain as well as inflows from adjacent rivers, creeks, streams and melting snow.
We can also increase the size of existing lakes by diverting inflows and blocking outflows. An example of this being the Great Lake in our Central Highlands.
As the water rises behind the dam wall the dam’s water becomes a potential energy reservoir. When the demand for electrical energy occurs the stored water is released from the catchment by opening an intake gate or inlet valve.
As all hydropower stations are built lower than the water catchment itself. The water is connected via a combination of canals, tunnels and pipes into the power station below.
The power stations are sometimes built underground. Depending on the type of turbine, the water either flows through or directly hits the turbine runner and causes it to spin. The height between the reservoir and the hydropower station determines how fast and with how much power the energy of water will travel and be transferred to electrical energy.
The energy of the moving water has now transferred to mechanical energy and after it passes through the turbine is released back into the river below the power station.
In addition to generating electricity and through controlled methods, a measured amount of stored water can be released into the downstream river to maintain waterways for both recreation and aquatic life.
Above the spinning turbine is a shaft which connects to the generator. Inside the generator is a rotor and a stator. The rotor contains many magnets. The rotor spins inside the stator which is filled with copper windings.
Now the mechanical energy is transformed into electrical energy which is carried by the copper wire and fed into a transformer.
The voltage is increased to allow for the efficient transmission of energy to a substation near your town, where it is then stepped back down to a lower voltage. The energy is distributed throughout the town or city where it is further stepped down to 415 or 240 volts.
The energy generated from water helps power Tasmanian households and businesses. It’s also sold into the national grid supporting Australia’s transition to a renewable energy future.
Renewable Energy Certificates, also known as RECs, are a hot topic of conversation, and confusion. What are they? How are they produced? How are they tracked? Here, Enel Green Power helps explain the currency of the renewable energy market. Video Rating: / 5
