Is renewable energy too weather-dependent?

| November 18, 2019

Fossil-fueled power plants cause pollution and climate problems, true enough, but they are generally a reliable source of energy generation on a large scale. One of the most productive steps in slowing climate change that we and the rest of the world must take would be to wean ourselves from our dependence on these primary sources of carbon dioxide emissions. Without that step, it appears the rapid warming of the mean world climate will continue, exceeding the temperature threshold that would somewhat mitigate the worst impacts of climate change as the century progresses. While the smaller-scale renewable technologies are on the rise, particularly wind and solar, they have a long way to go in achieving the needed drastic reduction in the use of fossil fuels. Wind turbine farms are multiplying and now produce between 6%-8% of the nation’s power.

5 New Solar Power Technologies in 2021

Article | April 5, 2021

In the last forty years, there has been a dynamic increase in the use of solar energy in the United States. As recently as 2018, an additional 10.6 GW of solar power was harnessed, bringing the country's total use up to 64.2 GW. Yet this apparently successful addition still only contributes 1.6% of the total electricity used across the States. However, with many new solar power technologies on the horizon, the increase could soon be much greater.

Toyota used AI to supercharge EV battery development and saved years of effort

Article | February 28, 2020

Scientists and researchers around the world are increasingly turning to Artificial Intelligence (AI)and so called Robo-Scientists to help them discover everything from new anti-biotics and drugs, through to new spray-on solar panel materials and vaccines, so it shouldn’t come as much of a surprise that AI is now being used to help develop new battery tech. “In battery testing, you have to try a massive number of things, because the performance you get will vary drastically,” said Ermon, an assistant professor of computer science at MIT, referring to how scientists traditionally hunt for new battery breakthroughs, and who led the new project to use AI to help them develop new promising batteries for Electric Vehicles.

COVID-19 and its initial impact on the energy sector

Article | March 26, 2020

As we continue to face an unprecedented global health crisis, our Head of Smart Generation Sales, Angus Widdowson looks at the initial impact the COVID-19 pandemic has had on the UK energy sector. With the UK on lockdown, many businesses closing and the majority of Britain’s workforce now working from home, COVID-19 is causing major economic disruption. It was covered in our Informer newsletter earlier this week that the growth in renewable generation in the UK gives us more resilience to tackle the challenges of COVID-19. Whilst the supply chain currently remains strong, as this pandemic continues, we are likely to see resource strain on operation and maintenance contractors. We expect naturally fuelled (wind, solar and hydro) plants to be more resilient than fuelled plant, given the lower risk to technical outages vs fuelled plant. Also, with renewable sites being dispersed across the country, we expect single point failures to have a lesser impact overall vs large thermal power generation. At this stage it’s unclear to see how COVID-19 will affect the development of new renewable projects but we are likely to see delays in the deployment of new wind and solar projects.

How Much Solar Does My Business Really Need?

Article | March 12, 2020

Solar, it’s everywhere. You’ve probably already installed it at home and now you might be looking to invest in it for your business. Something we see far too often in the commercial space is overcapitalisation or oversizing. Our client’s often say, “but Time Solar Installers have offered me a 100kW system and you’re only providing a 75kW system” or ��why haven’t you used my entire roof space?”. In this post I’ll explain the ins and outs of how we determine the size of a solar system for commercial businesses so that you’ll be equipped with the tools to ensure you’re not oversizing or over-capitalising!
