Battery capacity depends on user needs

 

There are many things to take into account when looking at an energy storage battery for your home or business. These include what you want your energy storage battery to do as well as its safety, performance, operating temperature and end of life recyclability.

Unfortunately many people only look at the initial purchase cost of batteries and this is what they use to compare different batteries. This doesn’t take into account what a battery may cost them over its lifetime or the cost to the environment of both the battery’s manufacture and end of life disposal. To make a realistic comparison of a battery’s cost you need to consider it’s full “cradle to grave” impact on all areas, including its safety during operation and it’s environmental impact.

Accelerating Climate Action

Amongst the G20 countries, Australia’s emission reduction target – a reduction of 26-28% on a 2005 baseline – is unusually weak, nowhere near what is required for us to play our fair share in meeting a 2°C Paris target.

The impacts that we are experiencing now at a ~1°C rise in average temperature are the forerunners of rapidly escalating risks as the temperature rises towards 2°C and beyond. An overview of these risks – worsening extreme weather, damage to natural ecosystems, disproportionate impacts on the poor and vulnerable – is given by the ‘burning embers diagram’ of the Intergovernmental Panel on Climate Change (IPCC). The series reveals a striking trend – as the science of climate impacts advances, severe impacts are now expected at more modest increases in temperature

Problems solved with battery storage

One of the biggest problems with the efforts to use renewable energy to produce large amounts of the energy consumed on a daily basis has been its inability to reliably supply power at the times it is most needed. This can and will be addressed with the installation of battery systems that allow households, businesses and energy network providers to store renewable energy for use at night or in peak periods.

Solar panels convert the sun’s rays into electricity during the day with maximum generation being between the hours of 11 to 3pm. Unfortunately, for most people unless you are home during the day 80% of this power gets fed back into the grid for very little return. Likewise, although energy generation through wind is now very efficient and cost effective the times when wind produces energy can be intermittent.

Batteries also reduce the amount of electricity that is exported to the grid from rooftop solar during the middle of the day. This has the capacity to significantly reduce variability and stabilise grid supply. Continue reading “Problems solved with battery storage”

Why will I choose energy storage batteries?

 

There are a variety of reasons that people choose to make use of battery storage. In the domestic market the most common ones are to reduce the price they are paying for ever increasing electricity costs by shifting power from their solar panels collected during the day to when it is needed at night.

There are many other people for whom the desire to be energy independent is the driving force, even if they still stay connected to the grid. This may be because of dissatisfaction with treatment from power companies or due to an unreliable supply. Continue reading “Why will I choose energy storage batteries?”

Our climate is changing now, with devastating consequences

Ice-covered Greenland isn’t normally associated with fires. But 2017 has seen a remarkable increase in the occurrence and severity of wildfires, and scientists are freaking out at the pattern of extreme weather events in the Arctic.

Thousands of acres of permafrost are burning in what appears to be Greenland’s biggest fire on record. And climate scientists are freaking out not just because the massive fires are unusual, but because they release large amounts of greenhouse gases and speed up the melt of the ice sheet and the carbon-rich permafrost. Continue reading “Our climate is changing now, with devastating consequences”

Off grid energy usage

 

There are many reasons why people live off the main electricity grid supply. They may live in remote areas where it is not economically feasible to connect to the electricity grid. Usually these communities have relied on diesel generators.

It may be a lifestyle choice where people want to be self-sufficient and take control of their own energy usage.

People that live at the end of electricity supply lines or Swer lines may have a lot of power outages and find it is actually more stable and economical to be off-grid or part of a local mini grid. Continue reading “Off grid energy usage”
