A Green Degree

This blog intends to bring a new perspective on all things 'green' and sustainable, covering (mostly) energy, politics, the economy & more, what I feel as the most pressing concerns we face. In short, sustainability needs to progress & become the social everyday. That's my passion, and our solution. Screw business as usual people!

This is simply a great idea, I just want to start by saying that. I love and am in awe of the vision and prospects this plan could bring to fruition, and it seems so ingenious to boot.

A future in which continent-spanning electricity grids feed the many hungry nations of Europe, Iceland and N. Africa has recently been plotted out by multiple energy ventures and renewable project giants such as DESERTEC and the EU. As you can see in the map above, the grid would stretch from the Saharan Desert, through all of Europe, up into Scandinavia and across the ocean to Iceland, connecting the entire region into one ‘energy-continent’.

This plan was initially suggested when people began noticing that energy projects in the UK, Europe and Iceland, as well as those in the deserts of Africa, were actually doing things thought irrational, uneconomic and plain stupid (think DESERTEC). Once this realisation set in, the idea of a pan-European/Saharan grid quickly formed.

With lines already laid connecting Ireland to the UK, France, the Netherlands, and now a record-breaking 950 mile long cable between Iceland and the UK, with plenty more in the works, this initially crazy daydream is rapidly becoming reality. 

What is the real beauty of this project however is the renewable side of things; the whole grid will be supplied by low-carbon tech alone, none of that fossil fuel nonsense. As each country associated with the super-grid generates their renewable energy through different means, such as geothermal in Iceland, wind in the UK, or hydro in the Scandinavians, it plays to each and every country’s specialities. Rather than laying new lines and sticking wind turbines somewhere that ain’t windy, the grid will transport wind energy to the required regions from those nations which can easily provide. 

With peak times being met by green energy flying in from abroad, for the states that have proven their worth in one or two particular renewable energy sources and produce surpluses at a consistent level, the monetary rewards are tantalising to say the least. Think of a scenario thus - France fears it can’t supply the energy needed to run its nation at full pelt, so it calls on the super-grid to supply some wind energy from us Brits, supplemented by some Swiss hydroelectric. Meanwhile, the Sahara (pumping out silly amounts of solar energy) is sending sunlight to Norway and Spain, and receiving a tasty return on their energy investment. It’s a complete win-win situation.

Whilst fooling around yesterday trying to avoid doing work and reading up on the world’s news via Twitter etc, a question popped into my head and sat there like an itch I needed to scratch, an itch to do with climate change and a very widespread, but often neglected form of green energy - hydropower. 

As my mind wandered, I began thinking about what effect a globally warming world, with its extreme weather events, climate weirding and melting ice, would have on the frankly massive industry of hydroelectric generation. Would it act to reduce the effectiveness of dams, or actually aid in powering them up; after all, climate change has done some pretty unexpected things in its time, and we are only just scratching the surface of weather system interactions and seasonal skewing.

I decided the best course of action would be to check out a few published papers/journals (of which links are available to at the end of this post) and garner a simple answer to the question, in turn informing anyone who reads this of the conclusions I came to. 

I went into this with two polarising thoughts. One, was that climate change, in this instance the global increase of temperatures over the next century or so, would act to reduce the effectiveness of hydropower through the evaporation of reservoirs, rivers and water sources, as well as a reduction in flow of the rivers/system feeding the dams. On the other hand, it may actually increase the power of HE, or at least cause no change at all, by increasing snow-melt, thawing seasons and rainfall, all of which would lead to higher river discharges and a larger water source for energy. So these were my two hypotheses so to speak. 

From the three top-cited papers I checked out, there arises a conclusion common in the scientific world, one that I have seen many times over; it’s variable. Now I know this is not enough for a rigorous answer to be put forward, but these papers are at least some of the top in the field of study, and if anything I am attempting to urge further study into it by readers and myself alike, so a future post may probe further, but for now, I’m taking these as a starting point.
