A new world record for tidal power generation

As many of you will know, we love keeping up to date with advances in renewable energy. At the end of August, the Pentland Firth tidal project in Scotland broke the world record for monthly electricity production by tidal power. The MeyGen project developed by the marine power generators ‘A…

How green is Hydroelectricity?

Large hydropower schemes account for the majority of the world’s renewable energy supply. Unlike wind and solar, hydroelectricity can provide a constant stream of renewable power, regardless of the weather or the time of year. Hydroelectric dams can be used to store power, and can quickly b…

Can we generate 100% of our energy from renewables?

In early May of 2016 Portugal covered all of its electricity demand for four days using only renewable sources, energy prices in Germany briefly turned negative, as renewables met almost all of the demand for a day, and the UK didn't use any coal fired power stations at all during several low…

Feed-in tariffs on rocky ground

Feed-in tariffs on rocky ground

The department for energy and climate change (DECC) has started a consultation on the future of feed-in tariffs (FiTs). The government is looking at phasing out the subsidy by 2018/19 but if the scheme can’t be put on an “affordable or sustainable footing” then payments of the g…

MCS strengthens procedures - but will it kill the cowboys?

Knowing that your installer (and the product they are installing) is going to do a good job is always important. In a new industry, with unfamiliar products and taxpayers money available to support it, it's even more important.  This is exactly what the Microgeneration Certification …

Beware: receiving grants from public funds may make you ineligible for feed-in tariffs

The feed-in tariff is intended to replace grants from public funds as the main way of incentivising microgeneration. So anyone awarded a public grant to install or buy generating equipment is in danger of not being eligible for the feed-in tariff (unless they repay the grant). There are some exem…
