Renewable Energy

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…

If you want to improve your carbon footprint but can't afford your own rooftop solar array, you can purchase clean energy credits and have renewable energy offset your power use. What is the cleanest energy? Despite how commonly the term ‘clean energy’ is used, there is actually no such thing. At least not in the…

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…

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…

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…

How to choose and properly size a solar home battery system. Home battery systems have recently improved in two substantial ways, and the first big improvement is in the batteries themselves. Lithium-ion batteries on the market today are much more robust and functional than the lead-acid batteries we have relied on…

In 2019, renewable energy sources accounted for the majority of power used in the US, the first time since 1885 that coal was not the country's main source of power. Energy generated by fossil fuels has dominated the globe for generations. Some countries have pushed for a faster transition to cleaner fuels than…
