What type of coolant should you use for your solar system?

I just came across an interesting item describing the three most common types of coolant for solar hot water systems and some of their properties. The article seems to be written by the manufacturer so there may be a bit of bias, but it does highlight the issues inherent in coolant selection. It is short […]

The same old energy mix — The Japan Times editorial

The same old energy mix — The Japan Times editorial. I follow the folks that write Japan Safety: Nuclear Energy Updates and they just posted an article from the Japan Times where they look at the current government’s plans for energy sustainability over the next few decades. The picture is disturbing in light of the […]

Sweden have successfully used taxes to reduce environmental damage.

Sweden has shown a longstanding commitment to the environment, significantly reducing greenhouse gas emissions, air pollution and nitrogen leaching. Renewables supply more than a third of its energy needs. Sweden has set itself tough targets for the future, however, and must continue to innovate if it is to meet them, according to a new OECD…

A ‘bionic leaf’ turns solar energy into chemicals and fuels

The site at the link below (“A ‘bionic leaf’ …”) presents a really interesting idea on how to store energy from the sun and at the same time act as a temporary carbon sink by absorbing CO2 for creation of the chemicals.  I will be looking forward to seeing how this plays out when they […]
