All things ‘green’… and there’s money to be made! Leading climate scientists have only just warned that our world is dangerously near exceeding the 1.5oC upper limit for global warming, a mere eight months after this target was established at the Paris climate summit. The negotiations, deemed highly successful at the time, went further than the previously held 2oC limit beyond which climate change would start to become catastrophic – and possibly irreversible. Smart Electrician The Internet of Things for Electricians The reasons are clear – the world is simply not de-carbonising fast enough. At Smart Electrician, we have a mandate to look at all things high-tech electrotechnical, including – of course – the burgeoning Internet of Things (IoT) sector. However, we also include the latest sustainable technologies, not least because we all (presumably) want to save our world, but also because there’s money to be made in saving <strong>energy</strong> and installing the systems. Sustainable <strong>energy</strong> & the latest state of the technologies Smart homes are a key element of the electricity industry Solar PV systems & how to install them 10 Helping electrical contractors to benefit from the <strong>energy</strong> efficiency issue new trends that will impact green buildings So, we come to this issue, which a cursory glance at page 7 will show is largely devoted to sustainable homes and buildings (which are also smart) and improving <strong>energy</strong> efficiency using the latest ‘green’ technologies. But first, back to that pesky 1.5oC limit, already so close to being exceeded. To avoid global warming catastrophe, the world will have to decarbonise at some speed, to the extent that the world must have no coal-fired power stations at all by 2025. That’s not all – by 2030 the internal combustion engine will need to be finished, whatever the Jeremy Clarksons of this world think. Even these measures will apparently not guarantee a rise of no more than 1.5oC, yet the task is enormous – especially as while the IoT can help save lots of <strong>energy</strong>, the billions of electronic devices of which it is comprised also use increasing amounts of electrical <strong>energy</strong>. Still, all this means that increasingly clever use of the IoT in smart homes, buildings, grids and sustainable devolved power generation will also be critical in keeping to the 1.5oC limit. And for smart electricians all of this means extra work, and lots of it for many years. Better get smarter still….and fast… So, in this issue of Smart Electrician, we bring you a veritable smorgasbord of latest ‘green’ trends and technologies – the renewables and electricity markets, the benefits for smart electricians, sustainable <strong>energy</strong> and smart controls, smart homes and grids, solar PV power generation (and how to install it), <strong>energy</strong> saving electrical protection and ventilation efficiency. That’s not all, as we also cover a method of sending electrical <strong>energy</strong> over data lines to drive small machines and devices. This, Power over Ethernet (PoE), has been around for years in industry, but to date even many smart electricians are not fully aware of it - so take a look…. ….have fun!
