Energy efficiency and the fight against climate change

| September 18, 2019

Investments in renewable energy have exceeded $1 trillion over the past three years. Solar and wind, along with hydro and geothermal systems, are providing low-cost alternatives to fossil fuel-based energy. With the rapid fall in the cost of energy storage, the prospect of transitioning grids to full reliance on renewable energy is now closer than ever. Governments from the United Kingdom to New York State have pledged a net-zero carbon economy by 2050, an unthinkable goal just a few years ago. In this race to a net-zero carbon economy, energy efficiency and infrastructure maintenance will play a fundamental role, on a scale similar to the construction of green field renewable energy projects. Estimates show over one third of energy in American residential and commercial buildings is wasted, from lights in unoccupied rooms, to poorly insulated buildings and inefficient air conditioning systems.

OPTIMIZING COGENERATION POWER PLANTS TO MANAGE RENEWABLE ENERGY EFFICIENTLY AND ECONOMICALLY

Article | February 11, 2020

A cogeneration, or Combined Heat and Power (CHP), plant uses a heat engine or power station to produce electric and thermal energy simultaneously from a single fuel source. A primary benefit of using a cogeneration system is that it can capture thermal energy for heating that is otherwise wasted in a conventional power plant. Utility companies today face the challenge of transitioning to the utilization of renewable energy for both electricity production and district heating systems.

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.

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.
