How to produce free electricity?

Free electricity can be produced by utilising the abundant natural resources around us. Choosing a residential green energy system can help in making  long- term savings and protecting the environment too.

Free renewable energysources are all around us. Some of them are the sun that shines, wind that blows and rivers that flow. Geysers that erupt, tide that goes in and out and radioactive materials that decay are all free renewable energy sources.

We can generate our own energy by converting these basic forms of energy into a form that is useful to us. It would require equipment or infrastructure like solar panels, wind turbine, dam, nuclear power plant etc.

It would be ideal to consult the municipalities or councils before going for a renewable energy system. Each state varies in the way they regulate renewable energy systems.

To make renewable energy installation easier, the government offers many incentives and tax credits for individuals. It applies to systems like solar panels, wind turbines, geothermal heat pumps and solar water heaters.

An appropriate usage of natural resources, help us produce free electricity in the following ways.

Residential solar panels

A solar power system captures every ray of sunshine that touches the roof and convert it to electricity.  Government subsidies, tax credits and incentives help many to go for solar panel installation.

Most of the solar companies offer a no-obligation assessment to determine the best installation sites. Solar panel installation is very important because the efficiency of solar panels depends on how well it captures maximum sunlight.

Energy generated by solar panels can be used right away. This would either eliminate or reduce electricity bills.

The excess energy produced by panels can be exported to the grid. The feed in tariff provided by government is another way of savings made by the solar power system.

A battery storage system enables one to store excess energy. It can be used when there is power outage It can also be used when the system has less or no production due to weather condition

Wind turbine

To provide free electricity for home, there is no need of huge wind turbines. Even a small propeller installed in a windy area can work wonders with electricity bills.

Professional advice has to be sought before installation. They can assure about the safety of turbines. Propelling the turbine blade requires ample wind. Professionals can help in locating such best places.

The electricity generated by the turbines can be used as such or stored in a battery for later use. It can even be exported to the grid.

3. Solar and Wind Hybrid Systems

A Solar and Wind Hybrid Systems is perfect for electricity generation in a place where there are sunny days and windy nights. It compensates the drawbacks of solar power system and wind power system.

It would capture the solar energy during daytime and convert it into electricity. At night when there is no sunshine, it would capture wind energy and convert it into electricity.

The excess produced can be stored in a battery. One can easily disconnect from the grid provided they have a Solar and Wind Hybrid Systems with battery storage system. It will meet all the energy needs of a house.

Micro hydropower Systems

Micro hydropower Systems divert the flow of water through a small turbine. The current generates free electricity 24 hours a day.

The flow of water is more continuous and reliable than wind and sun. That makes a micro hydropower system better than a hybrid system.

This system can be used to power an isolated home or a small community. It is essential to have a running stream on the property.

In areas where water flow is maximum and solar energy is minimum in winter, it would be better to use a micro hydropower system along with a PV system.

Solar Water Heaters

Installation of a residential solar power system is expensive. Solar water heaters are an affordable way of capturing natural sunlight to heat water.

This system works on the thermosiphon principle. Solar water heater is designed to provide hot water without consuming expensive electricity. It would make a huge difference in electricity bills. It is environment friendly as well.

Geothermal Heat Pumps

Geothermal heat pump is a highly efficient renewable energy technology that is gaining wide acceptance for both residential and commercial buildings.

It is used for water heating, space heating and cooling. Instead of producing heat through the combustion of fossil fuels, geothermal heat pumps depend on naturally existing heat.

It uses the earth as a heat source. It uses the heat below the earth’s crust to heat homes and offices during winter.

These systems use a closed loop of pipes to pump fluid through an underground channel. It is pumped into the home and back to

underground again.

Inside the home, a heat exchanger uses warmth from the pipes to heat living spaces while using minimal energy.


Factories generate a lot of biomass waste and this can be used to generate electricity.  Biomass fuels include scrap lumber, forest debris, certain crops, manure, wood chips, timber offcuts, paper products, animal manure and sewage.

When biomass waste is heated, it produces steam and this steam is used to run turbines which produce electricity.

At home, we can burn dry biomass in a wood burner for heating. This heat can be used for water heating.


Biogas can be produced from raw materials like agricultural waste, manure, plant material, etc. It is useful for farmers who have to dispose of a lot of animal and plant waste.

Biogas is used as fuel for combustion engines. It converts it to mechanical energy which powers an electric generator to produce electricity.

This biogas can be used instead of natural gas for heating, cooling, cooking and producing electricity.

A biogas plant is suitable for larger farms only as it requires maintenance and operational attention.

Diesel generators

Diesel generators can be used for electricity generation in residential and commercial sectors. Being expensive not all can afford a diesel generator.

Ensure minimum electricity wastage with proper insulation, energy-efficient light bulbs, gas cooking, solar water heating etc.

Such a practise along with any type of home power generating equipment can lower electricity bill to a greater extent.

Iron air battery backed by Bezos and Gates promises storage at fraction of cost

form energy battery storage

A US start-up backed by some of the world’s richest people has unveiled the chemistry behind its rechargeable “iron-air” battery storage technology, which it claims can deliver electricity for 100 hours, for one-tenth the cost of traditional lithium-ion batteries.

Boston-based Form Energy, which has attracted high-profile investors the likes of Amazon boss Jeff Bezos, Bill Gates’ Breakthrough Energy Ventures and Australia’s Macquarie Capital, said this week that the long-duration battery was made from iron used in combination with water and air.

The technology works on the principle of “reversible rusting” which, as Form Energy explained, means that when the battery discharges it “breathes” in oxygen from the air and converts iron metal to rust and then, when charging, the application of an electric current converts the rust back to iron and the battery breathes out oxygen.

“We conducted a broad review of available technologies and have reinvented the iron-air battery to optimise it for multi-day energy storage for the electric grid,” said Mateo Jaramillo, CEO and Co-founder of Form Energy. “With this technology, we are tackling the biggest barrier to deep decarbonisation.”

In addition to unveiling the chemistry of their new iron-air battery technology, Form Energy also announced the beginning of a $US200 million Series D financing round led by ArcelorMittal’s XCarb innovation fund, which invested $US25 million.

ArcelorMittal will work jointly on the development of iron materials which the company will non-exclusively supply for Form Energy’s battery systems, which it will manufacture near the location of the previously proposed Great River Energy pilot project.

World’s largest floating solar farm – more than 2GW – to supply Singapore

sunseap floating solar pv system

Singapore’s floating solar PV ambitions continue to grow, with local outfit Sunseap proposing to build a giant 2,200MW project on a reservoir on Indonesia’s Batam Island – the largest of its kind in the world.

The floating solar array, announced following an agreement with the Indonesian government, would be paired with more than 4,000MWh of energy storage, making it one of the world’s largest solar and storage projects – floating or otherwise.

Sunseap said the installation of the $US2 billion solar farm on the Batam Island reservoir, located just 20km from Singapore, would have the added benefit of reducing evaporation from the important fresh-water source and could pave the way for similar scale projects across south-east Asia.

“This hyper-scale project is a significant milestone for Sunseap coming soon after we had completed Singapore’s first offshore floating solar farm along the Straits of Johor,” said Sunseap co-founder and CEO Frank Phuan.

“We believe that floating solar systems will go a long way to address the land constraints that urbanised parts of Southeast Asia face in tapping renewable energy.”

Why Roof Maintenance is Important

roofingRoof maintenance is part of the responsibility you shoulder as a homeowner. It involves many things like checking for leaks, cleaning your roof, inspecting seams and flashings, repairing broken parts and replacing damaged ones, and other repairs aimed at prolonging the life of your roof. When you entrust your house to roof maintenance professionals they can offer regular inspections, disinfection, cleaning, repairs, and other services aimed at prolonging the life of your roof. It is essential to regularly maintain your roof to last longer and not need any additional work done. You can also save money on roof maintenance costs if you get a professional roofer to do it for you.

When you have a roof maintenance plan, you will know what kinds of works need to be done to your roofs and which professional roofers you should contact to perform each job. For instance, if you have cracked and broken tiles, you need to have them replaced. If you have leaks and waterproofing problems, your contractor should send you a maintenance plan so that he can estimate how much work you will need to do and when.

Sometimes, roof maintenance is subdivided into emergency roof repair and preventive maintenance. Emergency repairs are usually performed when there is a leak or other kind of damage. These repairs include patching up any holes or cracks that may be present. Preventive maintenance works like making sure that the gutter system works properly and getting rid of leaves, branches, snow, ice, and other debris so that they don’t clog up gutters. You should also check for sharp pointed objects that could be doing damage to your roof.

Emergency roof maintenance is not only about fixing any existing damage. It also includes inspecting areas where there is potential for future roof problems. For instance, if your chimney is leaking, you need to immediately fix it. The same goes for a ceiling that is beginning to leak, a foundation that is beginning to cave in, or other areas that you suspect might have issues.

On the flip side, preventive maintenance is less routine maintenance. It is essentially spending less time on your roof. This would include things like replacing roof shingles, cleaning gutters, painting and other repainting jobs. By doing so, you prevent further roof damage from occurring. In addition, the routine maintenance included in this type of roof repair and replacement would be less expensive since you would not need to do roof repair if the damage was already present.

If you live in a hurricane or tornado zone, you must really maximize your roof maintenance time and efforts. For this purpose, you must hire a professional roofing company that has the proper tools, equipment and know-how to do roof maintenance properly and efficiently. This could include things like inspecting weather stripping, repairing leaks on pipes and gutters, cleaning windows, repainting, and other areas. The better your roof looks, the more value you add to your property. You will probably see your property’s value increase after any roof maintenance work is done.

Even if you do not live in an area that is prone to tornadoes or hurricanes, you still need to take note of your roof’s appearance. It would help if you could prevent the formation of debris on your roof. For this reason, roof maintenance services are great for adding curb appeal to your property. Whether you have a metal, asphalt or wood roof, debris can cause damage to the appearance of your property. In addition to devaluing your house, this type of problem can also be very unhealthy. Asphalt and clay roofs are notorious for causing problems with mold and mildew.

If your roof needs some type of maintenance, make sure that you are proactive about it. Contact a roof maintenance company as soon as possible for routine inspections and clean-ups. Keep in mind that prevention is always better than the cure. With proper preventive maintenance, you will save yourself money in the long run, while keeping your home’s value high.

Virtual Power Plant (VPP): What are they and their benefits?

virtual power plant home

Some of you may have heard of the term “Virtual Power Plant” in recent years within the solar system and battery industry. In this article, we’ll explain everything you need to know about VPPs and how it’s something you could benefit from in the future.


What exactly is a Virtual Power Plant?

virtual power plant explanation

A Virtual Power Plant or VPP is broadly defined as an interconnected and distributed network of a wide array of energy sources, predominantly solar and battery systems (This can include other energy sources such as gas generators and electric hot water systems among others).

The group of interconnected solar and battery systems can perform services that help the grid be more stable and efficient. The VPP operator centrally controls and monitors all the batteries within the network. Many of the VPP operators in Australia are also electricity retailers so they have access to the electricity wholesale market, however a VPP can operate independently of who your electricity agreement is with. 

Generally speaking a VPP is designed to create value for both the VPP operator and the participants in the scheme – usually through sharing of the financial benefits the VPP creates.


What are the uses and benefits of a VPP?

The playing field for VPPs is defined by the current regulatory system. This is currently under review, but as we speak the current options for VPPs to generate money are explained below.


1. Selling power at peak demand periods:

virtual power plant selling power

The most common and obvious source of revenue for a VPP is to sell power by discharging batteries at times of peak demand. While you have a fixed rate or fixed time of use rates for energy from your electricity retailer, the wholesale market is constantly moving. 

The wholesale electricity price usually fluctuates between 4c per kWh and 10c per kWh, but at different trading intervals within the year the price can jump much. For example on the 17th May 2021 the wholesale electricity price was around $6 per kWh at 6pm in NSW, VIC and SA. 

At this point all VPPs in each of those states would have discharged as much power into the grid as possible earning $6 per kWh. They can offer a very attractive rate back to the participants of the VPP for each kWh they contributed and still make a reasonable revenue.


2. Helping create a more stable grid:

virtual power plant grid stability

All power networks require energy generation and demand from electricity to be in balance in order to operate safely and efficiently. If there is a change or variation in either side of this equation then this can lead to power failures and blackouts.

Along with the major power stations there are smaller, more nimble and flexible power plants (often gas) that can ramp up or down at short notice. These plants operate in the Frequency Control Ancillary Services (FCAS) markets.

In some cases plants in this market are paid to ‘stand-by’ and be ready to switch on at short notice. VPPs can operate in this market as they can rapidly discharge power into the grid or charge power from the grid.

In some cases these batteries within these types of arrangements will not be able to discharge below a certain level as they need to have sufficient power on stand-by to meet grid’s requirements.

How you are actually paid for your participation in a VPP demands on how each program has been set up. Some programs offer a benefits sharing scheme through an attractive or bonus Feed In Tariff each time the batteries are utilised. Other schemes offer an upfront discount off the cost of the battery or a fixed payment each month.

Virtual Power Plants in Australia

tesla solar plan south australia

By now you might be thinking to yourself, “virtual power plants sound good, but how do we participate with this in Australia?” Let’s explore VPPs in this country and how it could play out in the future.

South Australia’s virtual power plant would have to be the most well known user case of this technology. It was launched in 2018 as a joint venture between Tesla, energy provider Energy Locals and the South Australian Government with the goal of having 50,000 potential homes fitted with solar and Tesla Powerwall battery systems within four years. This would be the world’s largest VPP with a power capacity of 250 megawatts.

So far, 1,100 Housing SA homes have been the recipients of solar systems and batteries installed with new Powerwall owners enticed with a subsidy from the South Australia Home Battery Scheme. As of writing (July 2021), the subsidy has been reduced to $2,000.  In addition, Tesla has been enticing homeowners with $220 per year in grid support credits.

The cost of the project will be funded by exporting electricity generated by these panels.  It has been kickstarted with a $2 million grant and a $30 million loan, which the SA government hopes will help lower electricity prices in the State by increasing the amount of competition. SA is known for having high electricity prices due to the lack of competition.

An analysis by Frontier Economics, an economics consulting firm estimated that the system would lower energy bills by 30 percent for residents in South Australia. Housing Trust residents will still benefit even if their home is deemed to be unsuitable due to rooftop shading and other issues.

The purported benefits that Tesla is touting include lower energy bills, protection against blackouts, as well as energy monitoring.

The Scheme is offering several incentives in order to attract participants. A solar system combined with a Powerwall will be installed free of charge (subject to eligibility).

Whilst the Scheme sounds promising and altogether utopian in it’s ideals.  One of the most obvious concerns is the fact that Tesla is an exclusive battery provider for the VPP, so it doesn’t come without its detractors.

No doubt, Tesla is an innovative and ambitious company tasked with delivering 50,000 units over the period of the Scheme.

But Tesla is known for their continued production delays and quality control issues with the Model 3 electric car over the years. So, it shouldn’t be a surprise if they encounter similar risks in quality control and supply chain management issues with the Powerwall.

There’s also the inherent risk of having a company as a bottleneck in production. Whether there’s a natural disaster such as an earthquake or fire occurring at a factory or global supply chain issues due to COVID-19 , relying on one company as the sole supplier represents a potential single point of failure.

There’s also the issue of the size of the solar panels being installed on roofs with only 5 kilowatt capacity, which is an issue during winter.  In winter, 5 kilowatts of north facing panels will only produce 11.5 kWh a day.  This isn’t much, considering the fact that a Powerwall 2 can store 13.5 kWh. Therefore, if an average household self consumes an average of 5 kilowatt hours of solar electricity per day, that leaves an excess of 6.5 kWh to be stored in batteries. That means it would take over 2 days to fully charge a Powerwall 2 with solar electricity. That doesn’t leave much of a buffer in case anything goes wrong.

Frequently Asked Questions (FAQ )


What are the Pros of a VPP?

pros and cons

The fixed feed-in tariff is generally higher than average for most VPP programs. Some offer a very high variable feed-in tariff rate, with some going as high as $1 per kWh or more.Buying a battery through a VPP can significantly lower the upfront costs to customers so can make battery energy storage affordable for more AustraliansBeing part of an exciting renewable energy grid system


What are the Cons of a VPP?

Some VPP programs require the household to provide their own battery upfront. The implication with this is that for existing battery owners, depending on their battery make and model, it might not be eligible. The other issue is that they don’t receive any upfront discount incentives.There’s a lack of clarity and transparency around the fixed and variable feed-in tariff rates. For example, Energy Australia is vague about what an ‘event’ is regarding discharge of a battery. So, as a household consumer you might get frustrated with the lack of control.  We recommend you exercise your  due diligence and shop before you sign that contract.Being part of a VPP means that you’re essentially giving up control and autonomy of your battery system to someone else (which is the main reason why people turn to them in the first place). The implication of this is that most VPPs won’t leave any reserve storage with your batteries, as being fed into the grid. So, in the case of a blackout, you won’t be covered.The lifespan of your battery may be shortened as the VPP can discharge electricity from your battery at will.


How much can I earn?

earnings from a VPP

The short answer to this question is it really depends on your VPP provider. Some providers may give you a fixed amount, whereas others may ‘pay’ you in the form of a discounted electricity bill. Through many of the programs we’ve seen the benefits look to end up in the $100-$200 p.a range depending on the size of the battery.

We recommend you do your due diligence and shop around with several providers before you jump in the deep end.


How can I participate in a VPP?


Virtual Power Plants have been offered by several retailers in Australia over the past few years. It’s important to take into consideration the type of battery that you install, as it will guide you as to which VPP you can join. Also note that some VPP providers may require you to install an energy management device or specialised software.

Should I join a VPP?

making a decision

Virtual Power Plants are highly touted for their purported benefits with creating a decentralised network of individual DERs acting as a power station. However, as listed above there are several issues that need to be addressed.

Another issue is to do with optimal efficiency of resource use. Let’s say person X has high energy requirements and therefore has higher demands on the network. Person Y who has excess battery power to give to person X, but is connected a long distance from him. This poses an efficiency problem as there exists an equity issue between consumers. There’s also an issue not accounting for individual households specific energy requirements and usages.

Hence, the trend of moving away from the simple VPP model, and towards an upgraded and more reliable “2.0 model”. CSIRO is leading the way with their Virtual Power Station 2 project which will provide more transparent information to all parties to the network which benefit from it. In particular it will help the supply side of the network, where low daytime energy consumption worsens the issue of oversupplying from solar.

So, at this stage we would say that a Virtual Power Plant isn’t currently worth being part of at the moment due to the reasons listed above. However, over time as more VPP players enter the market, hopefully this will increase the level of competition that exists and so improve the technological aspects of the network as well as improved feed-in tariff rates.



Virtual power plants are a cutting edge decentralised energy platform that have the potential to radically transform the renewable energy landscape in Australia. Currently, we’re still in the early developmental stage of this exciting technology with a lot of potential in providing households with cheaper electricity and greater autonomy and less reliance on the conventional grid system. Watch this space for future growth.
