Forms Of Clean Energy

clean energy

Sources of clean energy don’t emit carbon dioxide or they emit just a little. There are several sources of clean energy such as hydroelectricity, bioenergy, and wind energy. These just name a few in what we learned at school.

What Is Clean Energy and Why Do We Need It?

Clean Energy
As mentioned above, clean energy is a source of energy that has little or no carbon dioxide (CO2) emissions.
Australia has some of the world’s best clean energy sources and many of these sources are sending power to home today. Clean energy sources such as solar power and wind power have the ability to meet the growing power needs in Australia without adding to the greenhouse gas emissions in the air.

Have you ever wondered why we need clean energy? If the people of Australia don’t change the type of energy that we use, there is a risk of suffering the harmful effects of climate change. Today, about 50 percent of Australia’s greenhouse gases occur in the stationary sector. This includes the generation of electricity, fuels that are consumed in manufacturing, commercial and construction, and domestic power such has power for heating and cooling. If we are going to make a change and protect the environment, clean energy education is important so that we can make a change.

Being Energy Efficient

Changing to low-energy light globes

Energy efficiency means reducing the amount of energy that we demand and use. If we use energy efficiently, we can cut the greenhouse gas emissions by up to 80 percent by the year 2030. Each year, the average home in Australia is responsible for generating over 7 tonnes of emissions. By making small changes in how you use or don’t use energy, it can have a major impact on reducing greenhouse gas emissions.

Being energy efficient is not as difficult as you may think. It can be as simple as:

• Changing to low-energy light globes
• Always turning off appliances at the point of power
• Buying products that are produced or grown locally
• Reusing or recycling items
• Leave the car at home and walk or ride a bike to your destination
• Use the sun’s natural energy to dry your clothes or to keep you warm
• Take on bigger projects such as installing solar water heaters, installing insulation at the home, plant trees or install window blinds to provide shad to the home on hot days, and connect the home to a clean energy source.

Types Of Clean Energy
Wind Energy
A wind turbine is used to capture the energy of the wind. It is then converted to electricity in the following way:

The force of wind is what causes the blades of the turbine to turn. The turning motion is transferred into a gearbox through a generator. This generator can produce energy which is then fed though a transformer to a substation. A wind far is a group of wind turbines that are located together. Wind farms are most effective in areas that have strong, consistent winds. Some of the best places in the world for wind farms are right in Southern Australia.

Solar Photovoltaic Power
Solar photovoltaic (PV) are the panels that you see installed on the rooftops of homes and businesses. When you install solar PV on your home, it is like having a mini power station on your roof. If can actually supply power to your home without needed to be connected to the electricity grid. This is especially beneficial for homes and businesses in remote areas. Of all the continents in the world, Australia has the highest average of solar radiation. Because of this, Australia could be the leader in solar energy generation.

Solar thermal involves generating electricity using the energy from the sun. Large, polished mirrors are used that are capable of reflecting the sun’s rays to heat a liquid. This would crate steam which spins a turbine and then powers a generator to produce electricity.
Passive thermal energy is another form of solar thermal energy. This is when you use the heat from the sun to dry your clothes or to warm up when the weather is cold.

Solar Water Heating

The cold water would flow into the inlet on the top of the heating panels.

Solar water heating uses the energy of the sun to heat up the water. Solar water heaters contain a tank for water storage as well as solar panels that are fitted onto the roof of the home. The cold water would flow into the inlet on the top of the heating panels. The panels are clean and flat and they act like a solar oven. They trap the sun’s rays between the layers. When the water passes through the tubes located under the panels, it is heated. This results in hot water flowing to the storage tank. Even if you live in the coldest parts of Australia, solar energy can provide up to 80 percent of the energy needed to heat the water.

Hydroelectricity
Hydroelectricity produces energy using the energy of flowing water though a hydroelectric power station. A turbine is spun using the force of flowing water. This operates a generator to produce electricity.

Bioenergy
Bioenergy is a form of energy such as electricity or thermal energy that is produced using organic matter or biomass. There re plenty of ways to capture the energy that is produced using biomass. Organic matter, such as sugar cane, can be burned. This can collect the gas that is released. It can be sued to run a generator which will produce electricity.
This form of energy is carbon neutral, which means that the amount of carbon dioxide that is released into the air. The waste that is burned is the same as the amount of CO2 and the sugar cane will absorb it when it grows. This is great for the environment.

Geothermal Energy
There re special granite rocks that are located deep below the Earth’s surface. The heat is trapped in layers of insulating sedimentary rocks. Electricity can be generated using this naturally occurring heat. To access this heat, wells are drilled into the Earth about 3 to 5 kilometers deep. Water is then pumped into wells and through the cracks that are created in the rocks. The heat of the rocks causes the water to heat up to the point that it turns into steam. This can turn a turbine, which will produce energy. The steam is then condensed back into water so that it can be used again.

Ocean Power
Ocean powers uses the tides and to ocean waves to generate electricity. To generate electricity, on the sea floor, a device with floats is mounted. The floats move back and forth with the natural movements of the water in the ocean. This is what powers a motor that produces energy.

Clean Energy Fast Facts
• In 2009, the use of wind energy has saved over 4 million tonnes of CO2 from entering the atmosphere in Australia. This is the equivalent of taking 950,000 cars off the road.
• There are many phone boxes in rural areas that have solar panels on top. These are very common today.
• Hydroelectric power stations are what delivers the majority of Australia’s renewable energy. There are over 100 hydroelectric stations around the country.
• Using biomass to create energy is not a new idea. People have been using animal waste and crop waste to cook their food and heat their homes for thousands of years.
• The best zero-emission electricity source is geothermal power. One megawatt hour of this type of electricity prevents about 1 tonne of CO2 from being released into the air.
• The temperature difference in the ocean is capable of producing energy. The steam on the water surface can be passed though a turbine generator, which can create electricity.

The Benefits Of Custom Home Design

The housing market provides buyers with a barrage of plans from ready-made units. People are conditioned to adapt to existing designs instead of creating their own based on their unique needs. Custom home designers encourage individuals to opt for the latter and gain the following benefits:

1. A Budget-friendly Home

People are conditioned to adapt to existing designs instead of creating their own.

Pre-built homes will have set prices due to their design and other factors. Buyers cannot do much to lower their cash outlay except to look for cheaper units. If they build their own home, then they can modify different aspects of the house to make it fit their budget.

2. Absolute Freedom of Design

Every individual has distinct preferences. Families are all different as well. It is hard to anticipate what people will need in a home. Those who aren’t satisfied with what they see in the market can design their house with a unique spin to each room based on the occupant.

3. Further Changes are Unnecessary

Since everything will be built to the owner’s specifications, there is no need to make any further changes. This is unlike most homebuyers who often spend a great deal of money to renovate their purchase.

4. Supervise the Building Process

Owners can and often do supervise the construction in tandem with their contractor. This ensures that everything is going according to their vision. If something seems off, then they can make changes on the fly.

5. Base Models Available

These can then be altered by using more sustainable materials, expanding some rooms, adding energy efficient systems.

Designing from scratch can be overwhelming so most contractors offer base models to their clients. These can then be altered by using more sustainable materials, expanding some rooms, adding energy efficient systems, and so on.

Custom home designers have the power to make their dreams come true and live in a house that is truly close to their heart. It’s a financially viable option that deserves to explored.

Alternative Energy Initiative In Private High School

To bring down electricity waste and the utility costs, schools are now more focused on renewable energy products. By making use of energy savers, which includes LED lights, solar panels, and controlled energy management systems, schools are working for an affordable and environmentally friendly energy solution.

By making use of energy savers like solar panel, schools are working for an affordable and environmentally friendly energy solution.

Schools in Australia are focusing more on investing in student learning opportunities instead of wasting resources on paying excess electricity bills. Instead of maintaining an old electric system that pollutes the environment, schools are more focused now on greener approach and curb down greenhouse gas emissions.

The improve energy systems in private high school results in the better allocation of funds in structural and development programs, like upgrading of buildings and improving learning facilities. This results in the overall improvement in the teaching system and the school gain a better reputation with more students enrolling in.

Government supports to energy-saving programs are unprecedented. A government-funded National School Plan granted over $217 million to more than 5,310 schools in Australia. This program gave schools the opportunity to move to renewable energy apparatuses and increased energy efficiency. The powerful solar systems under the National Solar School Program 2016 give enough energy to power the equivalent of 4,600 households a single day.

The government program encourages learning about energy renewable resources and teaches students about everyday routines that can prevent generation of greenhouse gases. The issues faced by most schools were tracking down the electrical savings and energy efficiency by using these new strategies. It became imperative for the schools to put investment in energy supply monitoring and management.

carbonTRACK for Learning Institutions

This is an effective energy management system which enables the school administration to monitor the purchase of energy and the generation of solar power. The data helps in determining the solar energy used and transferred for a specific period of time. The information is useful for the school administration as they can book their expense beforehand and deploy school funds appropriately towards energy and other infrastructural developments.

CarbonTRACK is a functional system that has embedded features to record electricity use and to point out instances of power depletion. With the proper implementation of carbonTRACK institutions have progressed to saving site energy up to 10%. This makes carbonTRACK hub management solution the ideal choice for energy monitoring and saving on energy consumptions.

Importance Of Right Driving School

Here’s the case for learning automatic
Between 2014 and 2017, more students applied for automatic driver’s licences than ever before. It is expected that the number of people applying for automatic licenses will rise in the years ahead. This is because automobile manufacturers are leaning more and more towards electric and hybrid cars. Fortunately, our experts anticipate this shift and are ready to train you the right way. When it comes to passing your driving test, you can be sure we will train to become an excellent automatic automobile driver.

Here are the top reasons we think automatic is the future.

Smarter Cars, Better Fuel Economy

According to some driving schools, the argument in favor of manual cars was that it offered better fuel economy than automatic transmission cars. Now, this argument is quite weak because automatic cars have special features that give them the edge over manual cars. These days, automatic cars come with up to 7 gears and this gives you better engine power. In addition, you notice better performance and improved fuel economy in current models of 5- speed automatic cars.

Mechanical Superiority
These days, automatic cars have mechanical superiority over the manual versions. Automatic cars are quicker, faster and more efficient than manual cars.

Stress Free Learning Means Stress Free Driving
It is easier to drive an automatic car and this is a great advantage for the learner because it builds confidence. In addition, there no stalling and you are not likely to backwards on a hill if you drive an automatic car.

Radiation Limits: Atomic Science Versus Nuclear Fear

A government document called NCRP-136 took a closer look at permissible radiation limits.

The data seemed to indicate that most people who received a small dose of ionizing radiation never had any negative effects associated with it. In fact, the data suggested that nuclear radiation actually had some positive influence on those exposed to it in small dose.

Nevertheless, the final conclusion was not that people would benefit by taking in a stronger dose of radiation. It instead recommended that regulations should simply be based on the idea that all doses of radiation are harmful to some degree. The authors of NCRP-136 went so far as to insinuate that these recommendations should be based on prudence rather than good science.

Scaring people with strong words and regulations certainly isn’t a very prudent act when the actual science claims otherwise. Only three uncontrolled releases of radioisotopes from civilian power facilities have ever occurred. The incidents at Three Mile Island, Chernobyl and Fukushima Daiichi caused more fear than actual injuries.

Announcing that no amount of radiation is safe cultivated a public fear of radiation that wasn’t justified when you look at the hard numbers.

Part of this has to do with how the media has a tendency to confuse nuclear weapons and atomic power facilities. The media would like us to believe that the incident at Fukushima Daiichi was far worse than it actually was because it involved the emission of particles that release radioisotope decay products.

Professor Wade Allison recently suggested in a lecture in Japan that we set the permissible radiation limit the same way that we set every other type of safety limit. Rather than asking how little radiation we can expose people to, Allison says we should set a baseline not to exceed.

No one suggests that we should lower the safety margin, but Allison illustrated that the annual permissible level could actually be nearly 1,000 times the current figure without causing significant DNA damage.

Lessons Learned From The Fukushima Daiichi Incident

Scientists and engineers are now taking a second look at the Fukushima Daiichi incident. Every new concern raised tends to create new safety requirements. This ultimately creates contradictions between the rules themselves and the science that those creating the rules referenced in the first place.

Every single death during the Tōhoku-Sendai disaster was caused by something other than ionizing radiation. People comfortably live in areas where natural geological processes create far higher levels of radiation than those measured in the forbidden areas of Fukushima Prefecture.

People living there were actually told they couldn’t return to their homes for potentially many years.

Decontamination efforts involve stripping away soil then coating the remaining ground with a material purported to reduce the number of radioactive particles that remain. Many residents have fallen into a deep depression and a few even killed themselves out of fear. This is all in spite of the fact that scientific evidence indicates radiation levels aren’t life-threatening.

These restrictions are based on prudence rather than science, and so ironically these rules have been very destructive. Professor Wade Allison proposed that the radiation limit gets raised nearly 1,000 times for this very reason. Even this level is far below the level at which DNA damage occurs according to a myriad of clinical studies that have been collected over a long period of time.

Some radiation experts are even coming around to this way of thinking, and they’re starting to say that their restrictive rules are hurting the Japanese economy. They’ve also created widespread panic, which has been far more harmful than the radiation itself.

Revoking this draconian measures would go a long way to restoring normalcy. Simply explaining the known facts about ionizing radiation would be a step in the right direction when it comes to educating the public.
