Renewable Energy

In simple words Renewable energy is produced using natural resources that are constantly replaced and never run out. Just as there are many natural sources of energy, there are many renewable energy technologies. Renewable Energy Technologies such as turbines, wind farms, and solar panels, can have a positive impact on the environment as a whole. Renewable energy can be successfully harnessed from a number of naturally occurring sources.

Today, solar power is everywhere! You can see them especially in homes, commercial buildings, and industrial warehouses. More and more families and institutions are using solar energy to power their living and workspaces. And what is more! It is a win-win solution to our planet earth as we utilize the lifetime power of the sun and does not pollute mother earth!

What is solar power?
Energy created by the heat and light of the sun is called solar energy. Solar power is produced when energy from the sun is converted into electricity or used to heat air, water or other substances. Solar energy can also be used to create solar fuels such as hydrogen.

At the end of 2017, there was 398 GW of solar PV installed around the world, meeting around two per cent of global electricity demand. More solar photovoltaic energy (explained below) is added each year than any other type of energy generation, thanks largely to the rapid cost reductions that have been achieved in recent years.

How does solar power work?
There are two main types of solar power technology, solar photovoltaic and solar thermal.

1. Solar photovoltaic
Solar photovoltaic (also known as solar PV) converts sunlight directly into electricity using a technology known as a semiconductor cell or solar PV cell.

The most common form of solar PV cell is typically encased in glass and an aluminium frame to form a solar panel. One or more panels can be installed to power a single light, cover the roof of a house for residential use, or be assembled into a large-scale solar farm generating hundreds of megawatts of electricity.

Solar PV panels are currently the most widespread type of solar PV technology, however other types of solar PV are being developed for targeted applications including PV that can be integrated into buildings, flexible PV and even PV paint.

2. Solar thermal
Solar thermal converts sunlight into heat (also known as thermal energy), which can be used for a variety of purposes including creating steam to drive an electricity generator. This heat energy can also be used to drive a refrigeration cycle to provide solar-based cooling.

There are two main types of solar thermal technologies.

Small scale thermal technology is used for space heating or to heat water (such as in a solar hot water system).
Concentrated solar thermal harvests the sun’s heat to produce large-scale power generation. It uses a field of mirrors to reflect sunlight onto a device called a receiver, which transfers the heat to a thermal energy storage system. Energy can then be released from storage as required, day and night.

What is bioenergy and energy from waste?
Bioenergy is a form of renewable energy that uses organic renewable materials (known as biomass) to produce heat, electricity, biogas and liquid fuels. The most cost effective and environmentally beneficial sources of biomass are typically wastewater, municipal waste and waste streams from the agricultural, forestry and industrial sectors.

Bioenergy technologies are well-developed worldwide. Globally, bioenergy was the source of half of all renewable energy used in 2017 and is forecast to rise exponentially. The International Energy Agency’s market analysis and forecast report, Renewables 2018, identified modern bioenergy as the ‘overlooked giant within renewable energy’.

A report for the International Renewable Energy Agency, Renewable Power Generation Costs in 2017, found the cost of electricity from biomass to be equal to that from onshore wind projects, and well within the range of maximum and minimum costs of fossil fuel generation.

How is biomass produced?
Biomass can be converted to bioenergy using a range of technologies depending on the type of feedstock (raw material), scale/size of the project and form of energy to be produced. Conversion technologies include combustion, pyrolysis, gasification, transesterification, anaerobic digestion and fermentation, or may be linked to processes such as biorefining.

Some conversion processes also produce byproducts that can be used to make useful materials such as renewable bitumen and even biomass-based concrete. Additional benefits include emissions reduction, waste disposal, providing support for rural economies, and improving air quality.

What is geothermal energy?
Geothermal energy is heat from the Earth. It is a renewable energy source with multiple applications including heating, drying and electricity generation.

How is geothermal energy produced?
Geothermal systems extract the Earth’s heat in the form of fluids like steam or water. The temperatures achieved determine the possible uses of its energy.

Geothermal energy in Australia
Australia has considerable geothermal energy potential, however the electricity produced is not financially viable in Australia due to three challenges:

finding it: identifying suitable geothermal resources
flowing it: producing hot fluid from the geothermal reservoirs at a high rate
financing it: overcoming the significant up-front capital costs associated with enhanced geothermal system technologies and the cost of transmitting electricity from remote locations.
How are we supporting geothermal energy projects?
Our purpose is to improve the competitiveness of renewable energy technologies and increase the supply of renewable energy through innovation that benefits Australian consumers and businesses. By connecting investment, knowledge and people to deliver energy innovation, we are helping to build the foundation of a renewable energy ecosystem in Australia.

The projects we have funded uncovered significant barriers in Australia, which helped inform energy developers and policy makers. This included a 1MWe pilot plant that ran at Innamincka Deeps in South Australia from April to October 2013.

What is hydrogen energy?
Hydrogen is the most common chemical in the universe. It can be produced as a gas or liquid, or made part of other materials, and has many uses such as fuel for transport or heating, a way to store electricity, or a raw material in industrial processes.

When it is produced using renewable energy or processes, hydrogen becomes a way of storing renewable energy for use at a later time when it is needed.

Hydrogen energy can be stored as a gas and even delivered through existing natural gas pipelines. When converted to a liquid or another suitable material, hydrogen can also be transported on trucks and in ships. This means hydrogen can also be exported overseas, effectively making it a tradable energy commodity.

Hydrogen in Australia
Like the rest of the world, the main use of hydrogen in Australia is as a raw material for industrial processes.

Renewable hydrogen use in Australia would help us to reduce emissions in those high-temperature industries as well as some transport sectors.

Several scientific and government reports have also found that hydrogen produced in Australia could be sold to the world. One report produced for us, Opportunities for Australia from Hydrogen Exports, calculated that global demand for hydrogen exported from Australia could be over three million tonnes each year by 2040, which could be worth up to $10 billion each year to the economy by that time.

What is ocean energy?
Ocean energy refers to all forms of renewable energy derived from the sea. There are three main types of ocean technology: wave, tidal and ocean thermal.

All forms of energy from the ocean are still at an early stage of commercialisation. Wave energy remains more costly than the other ocean technologies. Tidal range (see explanation below) has been deployed in locations globally where there is a strong tidal resource (for example La Rance in France, Sihwa in South Korea), while tidal stream (see below) has been demonstrated at pilot scale.

How does it work?
Wave energy is generated by converting the energy within ocean waves (swells) into electricity. There are many different wave energy technologies being developed and trialled to convert wave energy into electricity.

Tidal energy comes in two forms, both of which generate electricity:

Tidal range technologies harvest the potential energy created by the height difference between high and low tides. Barrages (dams) harvest tidal energy from different ranges.
Tidal stream (or current) technologies capture the kinetic energy of currents flowing in and out of tidal areas (such as seashores). Tidal stream devices operate in arrays, similar to wind turbines.
Ocean thermal energy is generated by converting the temperature difference between the ocean’s surface water and deeper water into energy. Ocean thermal energy conversion (OTEC) plants may be land-based as well as floating or grazing.

What is wind energy?
This energy type is electricity generated by harnessing the wind.

By the end of 2018 there was 600 GW of wind energy installed around the world, meeting almost six per cent of global electricity demand. It is expected to continue to grow its share of electricity generation globally, as well as in Australia.

How does wind technology work?
Wind turbines use the energy of the wind to spin an electric generator, which produces electricity.

Wind turbines are commonly located on hilltops or near the ocean. In some countries, wind turbines have also been built in the ocean, either floating on the surface or using giant pylons extending to the sea floor.

Wind turbines come in various shapes, although the windmill is the most common. Some international companies are also exploring ‘airborne wind’, which works like a giant kite.

As the wind does not continuously blow, researchers have developed ways to use energy from wind that also help to maintain a reliable supply of electricity, such as pairing wind farms with solar farms and/or energy storage such as batteries (see ARENA Action below).

What is hydropower?
Hydropower converts the energy of moving water into electricity. It includes a number of generation and storage technologies, predominantly hydroelectricity and pumped hydro energy storage (PHES). Hydropower is one of the oldest and most mature energy technologies, and has been used in various forms for thousands of years.

Hydropower now provides some level of electricity generation in more than 160 countries.

How is hydroelectricity produced?
Hydroelectricity is produced by passing water, usually from a reservoir or dam, through an electricity generator known as a turbine. As the water passes through the turbine blades, it drives the generator to convert the motion into electrical energy.

How does PHES work?
PHES uses water reservoirs as a way of storing energy. Excess energy, either from the grid or a renewable energy source such as a wind or solar farm, can be used during low demand periods to pump water from a lower dam to a higher one, essentially converting the upper reservoir into a giant battery.

The stored energy can then be released by returning the water through a hydroelectric turbine into the lower reservoir. Hydroelectricity can be generated almost immediately and at any time, making it possible for the power to be fed into the grid when it is needed, to help reduce surges, avoid blackouts, or meet spikes in electricity demand.

PHES can also produce large amounts of electricity over a long duration.
