Renewable Natural Gas (or not), RNG or Biogas Under The Microscope...

Many recent press releases are selling us on using public tax dollars to fund private enterprise in the shape of biomethanization plants to "revalorize" food waste and feacal sludge into biogas - what is Renewable Natural Gas & is RNG even a good idea. Recent articles have praised major public investments in…

Is this the safest and most powerful small home wind turbine yet?

We were told about the PowerPod compact home wind turbine appearing on a Kickstarter campaign, but having seen a fair few home wind turbines in the past that failed to deliver on their promises, Ecohome decided to investigate. Countless inventors are stepping up to the plate with the latest and greatest green…

Solar thermal collectors

Product of the month: Solar water heater with overheating protection

The flat plate solar thermal collector from Viessmann has a modulating collector to prevent overheating. Solar thermal panels in cold climates are at risk of freezing in winter, so in the North, we use a glycol mix as a heat transfer fluid. This prevents panels from freezing but introduces new problems in the summer…

All about solar thermal collectors

Choosing the right solar thermal water heater system. What is a solar thermal collector? A photovoltaic (PV) solar collector converts solar radiation into electricity , but a solar thermal collector is much simpler than that. It refers to a device that collects heat directly from solar radiation. That can be as…

Using reflectors to increase the yield of solar panels

A study showed that reflectors on solar panels can increase their performance by up to 30%. The continuing drop in cost for home solar power generation has led to a dramatic increase in the rate of installations, for both residential and commercial use. Increasing the yield through reflection could make that an even…
