Welcome to my 'All the Types of Energy' post!

First of all, I must congratulate you for taking the time to do your research on this topic of green living. We are in the middle of a climate crisis and knowing our sustainable energy options is crucial. I will list aal they types of energy for you. 

As a qualified teacher, I am passionate about education and the impact it can have on bettering our future. It is down to us individuals to do our research and make small changes to the way we live our lives. 

These small changes are easy to make and can have a big impact on our health, the health of our family and our environment. This website is designed for everyday people looking to make these changes. Here you will learn a legitimate way to go green. 

Let me be completely transparent with you, I am not here to pitch or sell anything to you. I am here to reveal and to assist you on your journey of going green! 

What is Energy?

Energy is everywhere! It's all around us and even inside us. Our whole universe is formed from energy. There are many various sorts of energy – from light and warm energy, to gravity, energy, and electricity. We all use a mixture of various sorts of energy a day.

Energy does all kinds of things for us. It moves our cars, cooks our food, plays our favorite songs, and provides light and warmth for our homes. Energy enables our bodies to grow and our minds think. So energy may be a changing, doing, moving, working thing!

Renewable Energy...

Renewable energy often mentioned as clean energy comes from natural sources or processes that are constantly replenished. for instance, sunlight or wind keeps shining and blowing, albeit their availability depends on time and weather.

There are a lot of awesome advantages of renewable energy - just like the fact it'll never run out! But it’s also important to remember the downsides - for instance, needing certain weather to get energy. 

Advantages...

​​​Renewable energy may be a super-smart choice for humans and therefore the environment. Here are a number of the large benefits of using renewable sources for our energy supply:

  1. They’ll never run out. The energy sources use energy that is natural and replenishable, they will always be there.
  2. They don’t damage our planet. These clean energy sources are non-pollutant, produce minimal or no waste products, and don’t contribute to heating - great news for the environment!
  3. They’re low-maintenance energy sources. Renewable energy facilities tend to need less maintenance than traditional generators. And as they are available from natural, abundant resources, the operating costs are generally lower too.
  4. They’re excellent news for regional areas. As most renewable energy projects are located in regional areas - far away from the large cities - they will bring economic benefits to those places. for instance, this might come from more people using local services.

Disadvantages...

As you'll see, there are many positives to using renewable energy. But what about any potential disadvantages? Here are a number of the explanations why renewable energy can sometimes present problems:

  1. Unreliable weather can affect energy supply. As renewable energy often relies on certain weather, this will impact the reliability of constant energy supply. For example:
    • Hydro generators need enough rain to fill dams for his or her supply of flowing water.
    • Wind turbines need wind to show their blades.
    • Solar panels need clear skies and sunshine to urge the warmth needed to get electricity.
  2. It’s hard to supply equivalent amounts as non-renewable sources. It is often difficult to get quantities of electricity that are as large as those produced by traditional fuel generators.

Solutions...

While we can’t control the weather, reducing the quantity of energy we use means we won’t need such an enormous supply. Having access to a variety of different energy facilities can help meet our constant energy demands. One clear thing is that having a balance of many different power sources may be a good solution to our energy problems.

Current science and technology are not ready for us to be 100% sustainable the way we live today, however, our top brains around the world are working on strategies to get there. We can also be more sustainable on a small scale while this research is taking place.

Types of Renewable Energy...

Biomass...

Biomass is an organic matter – anything that's alive or was a brief time ago - which will be used as an energy source. samples of biomass include wood, crops, seaweed, and animal waste. Biomass gets its energy from the Sun and maybe a renewable energy source.

Where does biomass get its energy from?

All organic matter contains energy stored from the sun – this is often where the energy in biomass comes from. Energy is stored by plants. When humans eat food that comes from plants, we use the energy they contain to maneuver and grow.

How is biomass used?

Burning biomass – like wood and garbage – produces heat, which may be utilized in homes, for cooking, and industrial purposes. Burning biomass also can generate electricity. In 'waste-to-energy' plants, organic waste is burned to supply electricity – by removing the waste products, this also saves on landfill space. it is a biomass bonus!

Biofuels...

Biofuels are created by the process of converting biomass into liquid fuels. Like any other gas, that can be transported and are favored for fueling vehicles. Ethanol is the most common biofuel. It is an alcohol made from fermentation biomass rich in carbohydrates.

Currently, corn is the largest ethanol source available to us. Biodiesel obtained from animal fats and ethanol extracted from corn can provide 0.5% of the total fuel market.

Flex-fuel vehicles are available on the market and they use a mixture of ethanol and gasoline. For instance, the E85, which contains 85% ethanol and 15% gasoline.

It is important to increase the availability of biofuel supplies. For this, companies in the U.S are making efforts to test crop residues, which include leaves, cornstalks, food waste, grass, wood chips, and trash. All of these items are potential sources of biofuel.

Some countries use these materials as a gasoline additive to meet ozone air quality standards or to decrease emissions. This is a step in the right direction but is not fully sustainable.

Biogas...

Biogas is a renewable energy source and is carbon negative. This means it can remove carbon from the atmosphere, creating usable energy from waste products. This is my number one recommendation for producing energy in the home. As with any energy production, safety precautions must be taken when implementing this at home.

Biogas is similarly obtained from organic matter. Biogas is often produced from raw materials like agricultural waste, manure, municipal waste, material, sewage, green waste, or garbage. The product is produced by anaerobic digestion. Methanogen or anaerobic organisms digest material inside a closed system. This closed system is named an anaerobic digester, biodigester, or a bioreactor. This process is the fermentation of biodegradable materials.

The mixture of gases produced from this process is biogas. Biogas is primarily methane (CH4) and CO2 (CO2) and should have small amounts of sulfide (H2S), moisture, and siloxanes. The gases methane, hydrogen, and carbon monoxide gas (CO) are often combusted or oxidized with oxygen. This energy release allows biogas to be used as fuel; it is often used for any heating purpose, like cooking. It also can be utilized in an internal-combustion engine to convert the energy within the gas into electricity and warmth.

Hydropower...

Hydropower is energy produced from moving water. This force is often extremely powerful and is driven by gravity. Hydropower plants use this energy to supply electricity. Hydropower comes from the Greek word "hydro", which suggests "water".

What is the Water Cycle?

The Water Cycle may be a continuous natural cycle that involves the autumn and movement of water.Here's how it works:

The Sun's energy evaporates water from oceans and rivers, drawing it upwards as water vapor.As the water vapor rises and reaches cooler air, it condenses and forms clouds.The moisture within the clouds eventually falls backtrack to Earth within the sort of rain or snow, replenishing the water within the oceans and rivers.

What causes water to move to?

The reason that water moves from status to low ground is thanks to gravity, which drives the movement of water. The force of moving water is often extremely powerful.

How is hydropower converted to electricity?

Hydropower is employed to get electricity in hydropower plants.

A typical hydropower plant system has three parts:

  • A power plant where the electricity is produced
  • A dam which will be opened or closed to regulate the flow of water
  • A reservoir where water is stored

What affects the quantity of electricity which will be generated during a hydropower plant? 

There are two factors that determine the amount of energy produced: head and flow.

Head is how far the water drops. Picture it because of the highest level of the water within the dam, to the purpose where the water enters the power-producing turbine. Flow is what proportion water moves through the system – the more water, the upper the flow. Generally, a hydropower plant with a high head needs less water flow than a plant with a coffee head to supply an equivalent amount of electricity.

​Hydropower is the largest source of green energy that produces 7% of the U.S electricity. Many hydropower facilities convert the power of flowing water into electric energy. Currently, in the U.S, the total hydropower capacity is 77,000 MW.

A dam in a river is a common form of hydropower. It generates power through the release of the retained water in the reservoir. The turbines then generate electric power. Hydropower plants do not generate air emissions. I would like to see more power being generated from waves. 

However, they currently affect the quality of water and wildlife habitats. These systems divert water from lakes or rivers and then direct it through pipelines to turbines. The U.S energy department is making efforts to design and operate hydropower plants that minimize the impact on rivers and creatures living in it.

But is this enough? To live sustainably we need to maintain the natural balance of life. Minimizing harm to ecosystems is still inflicting harm to our environment.

Geothermal Energy...

Geothermal energy comes from the warmth inside the world. It is often wont to produce electricity, to heat homes and buildings, and to supply predicament. heat is the only renewable sort of thermal energy.

What is geothermal energy?

Geothermal energy comes from the warmth contained within the world.

Where does the warmth inside the world come from?

The Earth's core - about 4000 miles below the surface - is formed from extremely popular molten iron that surrounds a cast-iron center. Surrounding the Earth's core is that the mantle, which is partly made from rock and partly of hot magma.

The outermost layer of the world is that the crust – this acts as an insulating layer. because the plates that structure the crust drift away and push against one another, they will cause the crust to crack or thin, allowing plumes of hot magma to get up into the crust.

How can we access geothermal from below the Earth's surface?

To find geothermal reservoirs on the brink of the surface, exploratory wells are drilled to look for reservoirs. Once a reservoir is found, production wells are drilled to bring predicament and steam to the surface.

The hot water and steam are wont to generate electricity at power plants on the brink of the assembly wells. Wells then returns the used fluids to the reservoir.

How is heat used?

  • Heating: heat is often won't to heat buildings.
  • Industry: dying cloth, drying fruit and vegetables, washing wool, manufacturing paper, pasteurizing milk, and drying timber products all use the warmth from geothermal water.
  • Hot Spring Bathing & Spas: for hundreds of years, people have used hot springs for cooking and bathing. the first Romans are famous for his or her love of geothermal baths!
  • Agriculture & Aquaculture: Warming greenhouses that grow flowers, vegetables, and other crops. It also can help speed up the expansion of fish, reptiles, and amphibians.

​The earth’s core is around 4,000 miles below the earth’s surface. It can reach 9000 degrees Fahrenheit. The geothermal energy or heat flows outward from the earth’s core and heats the surrounding area. As a result, it can form underground steam and hot water reservoirs. We can tap these reservoirs for a wide range of uses including electricity generation and heat building.

The potential of geothermal energy in the upper six miles of the earth’s crust which accounts for 50,000 times the power of all the gas/oil resources available on earth. With figures like this it is easy to presume that this would be our most viable option.

However, this is not currently a perfect solution because this energy source has been found to hurt our environment. Science and technology are developing every day. This might be a viable source in the future but I am concerned about the damage we will cause while investigating this energy source.

Solar...

Solar energy is energy produced from the sun. It's renewable energy, which suggests it'll never run out. solar power is often converted into electricity or wont to heat air, water, or other fluids.

What is solar energy?

Solar energy is heat and lightweight that comes from the sun's rays. this is often referred to as energy, because the sun radiates (or sends out) an enormous amount of this energy a day.

How is solar power used?

Solar power is captured when energy from the sun is converted into electricity or is employed to heat air, water, or other fluids. Electricity from solar energy is employed in people's homes, in schools (like yours!), and to provide power for equipment like telecommunications and water pumps. There are two main sorts of solar power technology:

  1. Solar thermal is when sunlight is becoming thermal energy or heat. Most solar thermal systems use solar power to heat space or water. An example of this is often a solar predicament system.
  2. Solar photovoltaic (PV) is when we directly convert sunlight into electricity, using photovoltaic cells. For an example of a PV system, just search – the solar panels on the roof of your school are using PV cells to get electricity right now!

What are the advantages of solar energy?

Solar energy comes full of benefits. Here are a couple of reasons why solar energy is so awesome!

  • It's renewable, which suggests we'll never run out of it.
  • It's easy to get – once solar panels are installed and are running at maximum efficiency, they only need a little amount of maintenance.
  • It's silent – PV cells make no noise in the least as they turn sunlight into usable electricity. So we will enjoy the peace!
  • It's non-polluting. Solar electricity power plants produce no emissions when they're up and running.

Why is solar power a sensible choice in Australia?

Australia is one of the sunniest countries within the world, making it a perfect place to capture the sun's energy for solar energy. And while we humans got to take care under the recent Aussie sun, PV cells love nothing quite an honest dose of sunshine! When the sun hits these cells, the sunshine causes the electrons to flow, which generates electricity.

Passive Solar...

Solar uses the infinite power of the sun. We can use solar energy to produce diverse electricity, providing us with options for lighting, electrical appliances, and heat.

Native Americans constructed their cliff homes in south-facing cliff walls because they understood that the sun moves low across the southern side of the sky during the winter. Native Americans knew the cliff’s massive rock would absorb heat in the winter season and protect them against snow and wind. Similarly, the design of the cliff dwelling would block the rays of the sun during the summer. This way, they would keep their cliff houses cool in the hotter months.

The contemporary version of this design is known as “Passive Solar” because there is no usage of fans, pumps, or other mechanical machinery. The basic features are large, south-facing windows, which fill your house with natural sunlight. They encompass brick or dark tile floors, which can store the heat of the sun during the day and release the heat into your home at night. Some great examples of these homes are called Earthships.

Passive solar design technology and energy-efficient devices are always advancing in their abilities and efficiency. For example, energy-saving appliances with good insulation and weather stripping make a substantial difference in power and cost savings.

Wind Energy...

 The wind is just air that's moving. it's produced as differing types of land and water absorb the Sun's energy at different rates. Winds are often wont to generate electricity using wind turbines.

How does wind form?

As the sun heats the surface, its energy is absorbed in several rates counting on the sort of surface. For instance, areas of land will absorb the Sun's energy at a special rate to bodies of water. This uneven heating of the surface leads to moving air – what we call wind.

Can wind be used as an energy source?

The wind is often harnessed and converted to electricity using man-made structures called wind turbines. This electricity is often used for residential and commercial purposes.

How do wind turbines work?

Wind turbines convert the K.E. in wind into motion energy which generates electricity. Here’s how:

  • Moving air turns the blades of the turbine.
  • This is turn spins a low-speed shaft which is connected to the blades
  • The low-speed shaft is connected to a gearbox. Inside, an outsized slow-moving gear turns a little gear
  • quickly, and therefore the small gear then turns another shaft at high speed.
  • The high-speed shaft is connected to a generator. because the shaft turns the generator, electricity is produced.
  • Cables carry the electricity down the turbine tower where it reaches a transformer that changes the voltage of the present so it is often sent out on transmission lines.

For centuries, people have used wind power to meet their energy needs, for example windmills. Today, we use wind turbines, which are different from windmills in terms of functionality. Wind turbines are more efficient and sophisticated, capturing the energy of the wind via airfoils.

The average onshore turbine can produce enough power to supply 1500 households with electricity. Many people do not like the look of turbines, so one suggestion was to have them situated in the ocean. However, land appears to be a more viable option. Ocean wind turbines have been found to have an effect on marine life at the base of the turbine.

All the Types of Energy: The Final Verdict!

Energy is everywhere and generating usable energy is essential to living the lives we live today. Non-renewable sources of energy create a lot of power. However they create issues for our climate and will not be around forever.

The current climate crisis makes it vital for us to seek other forms of renewable energy that create less harm for our environment. They all work differently, have advantages and disadvantages.

Science and technology are always developing and because of this some sustainable energy sources will be better in the future than they are now. However, we need to act now and use the technology that is currently available to us to prevent the earth from heating beyond a point where we have control.

We have the science and technology to use renewable energy and be sustainable. We need to act. If you have any questions, please leave them below.
