Do we need carbon taxes in an era of cheap renewables?

| October 31, 2019

There is a growing consensus that the energy transition requires high carbon prices to succeed. But if wind and solar continues to be cheaper than coal- and gas-fired power, won’t the transition happen anyway due to market forces alone? According to the International Renewable Energy Agency (Irena), 77% of onshore-wind and 83% of utility-scale solar projects due to be commissioned in 2020 will have lower prices than the cheapest new fossil-fired generation — and that’s without subsidies (something that fossil fuels still enjoy). And the cost of much of this new renewables generation will be cheaper than the cost of keeping existing coal plants running.

More Solar Ready To Help Power Pumping For SA Water

Article | April 29, 2021

SA Water’s electricity supply is about to become greener and cheaper again with the addition of another major solar power system, and an even bigger installation to soon follow. The utility says more 7,300 solar panels installed at the second pump station on its pipeline between Swan Reach and Stockwell are now connected and ready to go. “The Swan Reach to Stockwell Pipeline spans across more than 50 kilometres inland from the mighty Murray across to the northern Barossa area, and therefore requires significant energy to pump clean, safe drinking water across such large distances,” said SA Water’s Nicola Murphy While the total capacity of this new solar farm wasn’t provided, Ms. Murphy said it will generate approximately 5,224 megawatt hours of clean, green energy annually. There’s more solar energy to come for this section of pipeline, with a further 16,000 panels currently being connected at the first pump station.

Is solar or wind a better way to power your home?

Article | February 25, 2020

A growing number of homeowners in the United States are turning to renewable energy sources to provide power for their homes. Solar power systems only need sunlight to power your home and vehicle, recharge large battery systems, and still allow you to sell extra energy to your utility company. Wind power can perform the same functions by producing energy from wind-powered turbines. Both depend on often volatile forces of nature, but overall, solar panels provide more consistent energy. Solar panels don't include moving components, as wind production units do. These and other differences play important roles in deciding which renewable energy option is best for you.

CORONAVIRUS CRISIS FAST-FORWARDS GREEN ENERGY 10 YEARS INTO THE FUTURE

Article | April 6, 2020

As businesses shut down and many work from home around the world, electricity demand has reduced in COVID-19 hotspots. This could have a knock-on effect for the renewable sector. China, where the outbreak first took hold, is the world’s biggest electricity consumer. Output from factories has been substantially diminished with many unable to return to their jobs in manufacturing. Due to the curtailing of industrial electricity use, cuts in energy consumption for 2020 could be equivalent to the power used by the whole of Chile, according to IHS Markit. In Europe, peak power consumption has also gone down. Italy, Spain, and the UK have all seen an average 10 per cent drop in energy usage with bars, restaurants, offices and factories, which remain closed as social distancing measures continue.

Artificial Intelligence in the energy sector: opportunities and challenges

Article | March 25, 2020

AI is certainly the talk about the hour nowadays. In high-tech industry, AI is the one with most potential. But before proceeding and discussing further on this exciting technology, we’d like to first understand what AI means-: As power is being generated from more volatile sources like solar and wind, the requirement is that power generation must react intelligently to consumption (and vice versa). With AI, we can evaluate, analyse and control participants connected to each other via these smart grids. With modern day emphasis on climate changes and increasing pressure to reduce CO2 emissions, we must find ways to have most of our power generated from renewable resources. The problem with renewable sources of energy are that they are unpredictable, which makes production of energy periodical and sometimes even chaotic. With renewable sources, there can be power outages or too much power generation which needs to be controlled. Smart storage, also known as Intelligent Energy Storage(IES) can effectively handle these disrupt changes in power supply.
