Not in my backyard is a common syndrome among the societies of the western world. Renewable energies are preferred by many in these societies, as long as they are somewhere else. I concur that there seems not much sense in building a solar power plant Scotland – the Sahara would be a far better place for such – nor that we should sacrifice protected places like the Cairngorms for a bit of wind energy. So what options remain, if we don’t want to trust nuclear power (and who wants to do that after Fukushima?) and are fed up with the emissions of “clean” coal? I want to introduce you to my three favourite ways on how produce harness green energy, while ensuring that the wild places in which we love to walk are not plastered with pylons or destroyed by other emissions.
Windside and Cypress Wind Turbines are Finnish manufacturers of wind turbines. No, don’t click away yet. They are pretty. They are small. They are more efficient than the normal turbines you know. You might even want to get one to help power your house! It is a vertical design, which can operate at a windspeed as low as 1m / second. And it doesn’t kill birds. It has proven that it is durable in extreme conditions, from the deserts of the Sahara to the snow-swept planes of the Antarctica. More commonly you find them on the roofs of Finnish summer cottages to power a fridge and light the house, though. They even have been used as an art installation!

Okay, selling you on wind energy is a hard game, and you are right, it’s fine for a summer cottage but might not be enough to power a complete outdoor shop’s electricity needs unless you put half a dozen on the roof of said shop. How about wave power then?
AW-Energy is a start-up which has developed a technology called Wave Roller, which exploits the surge phenomenon, a strong, ubiquitous and consistent natural phenomenon present in the world’s oceans. The back and forth movement of the tidal surge moves the plates of the Wave Roller, transferring the kinetic energy produced to a piston pump; this energy in turn can be converted into electricity. The whole setup has a low visual impact as it is under water – in 10 – 25 meters depth – and a pilot plant already has been tested in Orkney, Scotland, at the European Marine Energy Centre. The energy output of the technology is a lot higher as for the vertical wind turbines, and given that the ocean is in constant movement this presents a very reliable energy source.

Which brings us to number three, and my favourite, source of energy: Anaerobic Digestion. No, that’s not a fancy word for diarrhea, but the process which creates biogas. Biogas can be made out of a variety of materials, which have in common that they usually all are waste material: bio waste from industries and households, liquid manure, sewage, and waste paper, among others. Simply put, the feed material – the waste – goes into a reactor, sits there for for 12 to 21 days while the microbes go to work on it, transforming the feed material into fertilizer and – ta-da! – biogas. This biogas can be used in combined heat and power gas engines (producing heat and electricity) or being upgraded to natural gas quality biomethane – which you can put into your biogas powered car. Result: Transforming a waste product into energy and fertilizer, creating zero waste, a warm house, and power for your car.
While there are large scale biogas plants in existence, the main argument against them is that they are fed with especially grown energy crops as maize, which, in a world where famines are increasing, is not a smart use of resources. A better use case for biogas reactors is for decentralized energy production – think how remote small villages could produce energy for their households, powering their cars, and use the fertilizer on their fields. These biogas plants can be build partially underground with a low visual impact as well, and having been at a small scale plant I can testify that a bad odour – which some might fear – is not existent. All in all a wonderful affair.
So there are alternatives to large scale wind turbines in National Parks, in the middle of a fine wilderness. Getting the word out about these is what matters, as well as individual action – installing photovoltaic panels or a small scale wind turbine on your roof to help power your house, investing in energy efficient gadgets, and switching that TV off not only sends a sign, it also will decrease your costs in the long term!
