RENEWABLE ENERGY: THE CLEAN FACTS

Wind and sun oriented are controlling a perfect energy transformation. This is what you need to think about renewables and how you can help have an effect at home.
Solar Energy
Solar Energy
Sun powered, or photovoltaic (PV), cells are produced using silicon or different materials that change daylight straightforwardly into power. Disseminated galaxies create power locally for homes and organizations, either through roof boards or local area projects that power whole areas. Sun based ranches can produce power for a large number of homes, utilizing mirrors to think daylight across sections of land of sunlight based cells. Drifting sun based homesteads or "floatovoltaics" can be a successful utilization of wastewater offices and waterways that aren't naturally touchy. Sunlight based supplies somewhat more than 1% of U.S. power age. However, almost 33% of all new creating limit came from sun powered in 2017, second just to petroleum gas. Sun oriented energy frameworks don't create air toxins or ozone depleting substances, and as long as they are dependably sited, most sunlight based boards have not many natural effects past the assembling interaction.
Wind Energy
Wind Energy
We've made considerable progress from older style wind plants. Today, turbines as tall as high rises with turbines almost as wide in measurement prepare for action all throughout the planet. Wind energy turns a turbine's sharp edges, which takes care of an electric generator and produces power. Wind, which represents somewhat more than 6% of U.S. age, has become the least expensive fuel source in numerous pieces of the country. Top breeze power states incorporate California, Texas, Oklahoma, Kansas, and Iowa, however turbines can be put anyplace with high wind rates like ridges and open fields or even seaward in untamed water.
Hydroelectric Power
Hydroelectric Power
Hydropower is the biggest sustainable power hotspot for power in the United States, however wind energy is before long expected to assume control over the lead. Hydropower depends on water commonly quick water in an enormous waterway or quickly diving water from a high point and converts the power of that water into power by turning a generator's turbine sharp edges. Broadly and globally, huge hydroelectric plants or super dams are frequently viewed as nonrenewable energy. Uber dams redirect and decrease common streams, confining access for creature and human populaces that depend on waterways. Little hydroelectric plants (an introduced limit underneath around 40 megawatts), painstakingly oversaw, don't will in general reason as much natural harm, as they redirect just a negligible portion of stream.
Biomass Energy
Biomass Energy
Biomass is natural material that comes from plants and creatures, and incorporates crops, squander wood, and trees. At the point when biomass is singed, the compound energy is delivered as warmth and can create power with a steam turbine. Biomass is frequently erroneously portrayed as a spotless, inexhaustible fuel and a greener choice to coal and other non-renewable energy sources for creating power. In any case, late science shows that numerous types of biomass particularly from backwoods produce higher fossil fuel byproducts than petroleum derivatives. There are additionally unfortunate results for biodiversity. All things considered, a few types of biomass energy could fill in as a low-carbon alternative under the right conditions. For instance, sawdust and chips from sawmills that would some way or another rapidly deteriorate and discharge carbon can be a low-carbon fuel source.
Geothermal Energy
Geothermal Energy
In the event that you've at any point loose in an underground aquifer, you've utilized geothermal energy. The world's center is probably just about as warm as the sun's surface, because of the sluggish rot of radioactive particles in rocks at the focal point of the planet. Penetrating profound wells carries hot underground water to the surface as an aqueous asset, which is then siphoned through a turbine to make power. Geothermal plants commonly have low emanations on the off chance that they siphon the steam and water they use once more into the supply. There are approaches to make geothermal plants where there are not underground supplies, but rather there are worries that they may build the danger of a seismic tremor in regions previously viewed as topographical problem areas.
Nuclear
Nuclear
Atomic force, the utilization of supported atomic parting to create warmth and power, contributes almost 20% of the power produced in America. The United States has utilized atomic force for over 60 years to create solid, low-carbon energy and to help public protection exercises. The Energy Department's Office of Nuclear Energy's essential mission is to progress atomic force as an asset fit for making significant commitments in gathering our country's energy supply, ecological, and energy security needs. By zeroing in on the improvement of cutting edge atomic advances, NE upholds the Administration's objectives of giving homegrown wellsprings of secure energy, lessening ozone depleting substances, and upgrading public safety. Atomic force stays a significant piece of our country's energy portfolio, as we endeavor to diminish fossil fuel byproducts and address the danger of worldwide environmental change.
Bioenergy
Bioenergy
Biomass is a natural environmentally friendly power source that incorporates materials like farming and timberland buildups, energy yields, and green growth. Researchers and architects at the Energy Department and National Laboratories are discovering new, more productive approaches to change over biomass into biofuels that can replace ordinary fills like gas, diesel, and fly fuel. Bioenergy can help guarantee a monetarily strong and secure future while decreasing natural effects through: 1.Developing moderate homegrown fills and co-items 2. Propelling clean fuel sources 3.Generating homegrown responsibilities to help the development of the U.S. bioeconomy. Innovative work to change inexhaustible carbon and waste assets into feedstocks for transformation to biofuels, bioproducts, and bio power will reasonably grow biomass asset potential in the United States.
Hydrogen and Fuel Cells
Hydrogen and Fuel Cells
The Hydrogen and Fuel Cell Technologies Office (HFTO) centers around exploration, advancement, and exhibit of hydrogen and power module advances across various areas empowering development, a solid homegrown economy, and a perfect, evenhanded energy future. Hydrogen is the least difficult and most bountiful component known to man. It is found inside water, petroleum derivatives, and all living matter, yet it seldom exists as a gas on Earth—it should be isolated from different components. There are different homegrown assets that can be utilized to deliver hydrogen, including renewables (wind, sun oriented, hydropower, biomass, and geothermal energy), atomic force, and petroleum products (like flammable gas and coal – with carbon catch and sequestration). The U.S. at present creates in excess of 10 million metric huge loads of hydrogen each year, around one-seventh of the worldwide inventory.

Battery installations in Australia up 20%, here’s why

Last year the number of residential battery systems installed in Australia increased by 20%. The 31,000 battery systems that were installed is a remarkable number, considering Australia entered a recession in September last year for the first time in almost 30 years. This article considers some of the key drivers behind the growing market adoption […]

Last year the number of residential battery systems installed in Australia increased by 20%. The 31,000 battery systems that were installed is a remarkable number, considering Australia entered a recession in September last year for the first time in almost 30 years. This article considers some of the key drivers behind the growing market adoption of small-scale battery storage systems in the Australian market.

Reduction in Feed-in Tariffs

The rate solar system owners can earn for selling energy back to the grid (Feed in tariff) has fallen significantly in the last 2-3 years in line with decreasing wholesales prices. In fact in many states, the wholesale cost of electricity moves into negative prices in the middle of the day when rooftop solar system generation peaks.

Many solar system owners have export rates of up to 70% or 80% and have been left searching for alternative means to create value from their surplus energy. This has been observed as one of the underlying drivers to battery take up.

In our recent analysis, we can see that even with the lower solar feed in tariffs the economic case to install a battery does not stack up. There are other non-financial factors that we need to consider when assessing the demand for battery storage systems.

State-based Solar Battery Rebates

The below table outlines some of the battery schemes that have come out in Australia over the last 3-4 years.

 Current RebateLaunched in
South Australian Home Battery SchemeUp to $300 per kWh installed2018
NSW Interest Free Solar LoansInterest free loans of up to $9,000 to retrofit a battery2020
ACT Battery Rebate$825 per kW of Sustained Peak Output2016
Solar Victoria$4,174 per household2019

With some of these programs were introduced several years ago they have been progressively building awareness. Many of these schemes help consumers with the financial return of investment for their battery system whilst supporting grid stability and resilience.

The Emergence of Virtual Power Plants

Only 3-4 years ago Virtual Power Plants were in concept phase only with no programs available anywhere in Australia. In the last 12 months the number of options available to consumers has skyrocketed with many companies looking to get involved in a potential new source of revenue and customer loyalty.

See the below table which summarizes several of the main Virtual Power Plant programs currently available in Australia and the value they are offering customers.

Some of the above schemes, when coupled with a state-based rebate scheme can start to offer customers a reasonable return on investment with a payback period as low as 5 years for a good case.

Increasing Climate Change Awareness

Climate change has been at the center of politic debates in Australia for more than a decade with particular attention growing on the current Coalition Government’s lack of meaningful action and continued support of fossil fuel sectors.

In the global context, Australia is a relative laggard in introducing climate policy which is creating increasing tension within political parties and

Climate change rallies were coordinated across all major cities in Australia in the lead up to the pandemic and in research conducted by the Australian National University found that 52% of voters was important when deciding their vote in the 2019 Australian federal election. This percentage is expected to increase progressively over next decade.

One of the main actions homeowners can take to reduce their own carbon footprint is to install solar. While solar alone can tackle 30%-50% of the predominantly coal-based power used on the Australian grid, a solar and battery system can get that figure closer to 100%.

Inevitably this is strong motivator to buying batteries for environmentally conscious Australians.

Notably left out of the list of driving factors for battery demand is the cost of batteries. We have seen little movement in battery prices in the last few years with the average cost of batteries only dropping 3% since February 2020 according to the Solar Choice Battery Price Index.
