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!

I came across an article today priding itself on the subject of wind energy subsidies in the US and why investing in them any longer would be tantamount to breaking the law, and boy does the author do it with some vigour and confidence. Unfortunately, and I really doubt I will be the only one thinking the same thing, most of what this person writes is founded on ignorance, scientific falsehoods and a basic hatred for wind energy in any of its forms.

The article, titled ‘We Must Stop Subsidising Wind Power’, which you can find in the link at the end of this post, focuses on a myriad of detrimental effects the Federal Production Tax Credit (PTC), a hotly debated topic currently, as it stands to be shelved come the end of 2012, with so far no hope of a successor. While there are many powerful and well-informed societies, associations and individuals lobbying for its extension, its pieces like this which seriously undermine rational thinking.

Supposedly, American wind energy, and by logical assumption, the entire industry, is unreliable, severely expensive, economically damaging and highly dangerous to the environment, seemingly to the same degree that oil and coal are; a real and direct threat to the green side of life. It is simply deemed ‘not environmentally safe’. What an absolute load.

Let’s start with the first point, wind’s unreliability and thus pointlessly impractical employment as an energy source. The crux of the argument here is that due to the natural flux in wind strength and speed, turbines are entirely dependent upon fossil-fuel based sources to prop them up (I know) and therefore the price of this is passed onto consumers like you and me. Aside from this, it isn’t helping us reduce our emissions nearly as much as we hoped.

Yes, wind is unreliable as a quantity, just like market prices for fossil fuels or the accessibility of reserves, but this hasn’t stopped wind becoming THE primary renewable energy source worldwide, demonstrating the biggest growth rates and deployment percentages of any type. Not only this, but some of the leaders of free political-thinking in regards to clean energy sources have proven this is not the issue it is made out to be. Germany for instance powers over 8% of it’s needs through wind, and has demonstrated that the apparent reliance on oil or gas for baseload on the grid is not true; wind and solar alone can power a nation if handled rationally and smartly, something the US is quickly catching onto. Only last year, the US installed almost 7GW of wind, up 31% on 2010, and could meet 10% of energy requirements in six greedy states, a hell of a lot more than most, and installation prices have also dropped, hitting just $2.1 per watt, down 10 cents on 2010.

With smarter systems, demand-response software and upgraded grids, all technology which is not only well established and on the rise but relatively cheap to put in place, the apparent issues with fluctuating wind and lulls in power can be negated almost completely. Combine this with CCGTs and solar, a nation as hungry as America can happily guzzle electricity without so much as a mention of oil, coal or shale ‘something’.

Hypersolar is an interesting and thought-provoking solar company, whose main goal is to bring clean energy to the masses through the clever and sometimes ingenious use of science and technology. Though a relatively small name in the big world of solar energy (I hadn’t heard of them until now), they harbour some big ideas and have introduced some powerful technology into the mix.

They initially hit the industry running with their creation of a Hypersolar ‘layer’ for solar panels, which could halve the amount of individual solar cells needed, whilst upping their output by an impressive 400%. This layer would replace the traditional glass screen atop the cells, and would focus solar radiation onto rows of cells, therefore intensifying the light and producing extra juice. A neat invention to say the least, although I haven’t heard much else about the product.

This time round, they’ve decided to combine their solar expertise with an area of energy production which I, and no doubt many others, did really not expect. They hope that, with their new solar cell systems, they can imitate nature and the beautiful complexity of photosynthesis in order to create ‘clean’ and ‘renewable’ natural gas. Clean I hear you say, that ain’t right. 

By mimicing plants, the team plans to split water into its component parts, hydrogen and oxygen. This hydrogen is then combined with carbon dioxide, presumably they hope from the atmosphere itself, to create methane, a prime constituent of natural gas. As this carbon is from the air around us, not only does it suck CO2 from our dirty atmosphere, it then uses this to produce more fuel for us to burn. As it only requires water alongside this, it can be labelled renewable by the company.

The team also highlight that they believe the natural gas future is a very real one, but that the environmental faults of extracting and creating it is both dirty and expensive. Therefore this technology kills two birds with one stone, making the environment happier whilst still allowing a less radical switch to a NG dominated economy.

The Future of Renewable Energy

Currently, 82.8 million barrels of oil are consumed everyday. 30% of this energy is wasted. Energy forecasts for the year 2050 are 4:1 in terms of renewable energy to conventional energy consumption. While this number may sound positive, we have to incorporate the facts of life into the future energy equation i.e. there will be more people, there will be more devices, there will be more infrastructure, there will be more aggressive control mechanisms put into place to combat climate change etc. 

In order to reach that ratio, our renewable energy source has to produce an exponential amount of power to meet growth expectations. Already smart grids, wind turbines and solar panels are being aggressively installed in China. Japan is actively looking into this space. The US understands the need to be vigilant in this space in order to not face another OPEC crisis. With oil prices going through the roof, airlines industries on the brink of going sour, more aggressive funding needs to go into energy R&D to deal with this in a more punctual manner. Maybe we can expect some new developments in the field of hydrogen fuels. 

Lovely little video.

Incredible new video commissioned and released by the Planet Under Pressure conference in late March to highlight the newest epoch brought about by us, the Anthropocene. 

This video is beautiful and majestic in its depiction of how humanity has spread its influence across the entire globe, with animations overlaid on the Earth demonstrating road and rail networks, internet lines, shipping routes, flightpaths and so much more; it is literally a wonder to watch and behold the might of us humans. 

It boggles my mind to think how we have spread so far, built in every continent and country and literally blanketed the planet in our technology, for better or for worse. 

Everyone should watch this just to experience our power and understand our species just that little bit better. There’s even a non-narrated version if you just want to sit back and soak up the video in all its sheer wonder.

After just 14 months of preparation and the collaboration of 21 countries, the Indian state of Gujurat has just turned on the world’s largest solar powered plant, to the tune of $2.3 billion and a 600MW generating capacity. Given its size, this is more of a solar-city than a mere plant, coming in at 5,000 acres, producing as much energy as a well-oiled (forgive the pun) fossil fuel plant or nuclear reactor.

With the advent of this new addition to the grid, India plans of powering forward into the renewable future with goals of 15% by 2020, with current values sitting around the 6% mark. Now that’s not nearly as ambitious as some of the other keen-on-green nations, such as Denmark’s wild 100% mix by 2050, or the 30%-40% goals of the UK, Germany or other Scandinavian players, but it’s a huge step in the right direction. 

Given India’s stance on the global stage in the last climate talks, touting itself as a solar leader with the technology to back its claims, it would finally seem things are coming to fruition. Further investment of $400 million has been laid out for promotion and advancements, and residential solar is being pushed as the next step for India. 

Unfortunately, this latest project pales in comparison to the TuNur proposal in Tunisia, part of the DESERTEC initiative focused on building solar plants in the African deserts. This whopping 2GW plant will dwarf even the Gujarat attempt, and plans to be complete by 2016. This plant however takes the form of a concentrated solar power generator, whereby panels direct sunlight onto a single collecting tower, producing intense heats to boil water and spin turbines. 

The one question that does arise in reading these, to me at least, is that of how many more similar builds can be undertaken before space becomes a serious issue? In countries devoid of deserts of wide open, flat spaces (think Japan, SE Asia or many EU nations), there is unlikely to be room for multiple builds in similar scale to the Indian or Tunisian effort, and unless urban spaces are integrated fluidly, it’s a real stumbling block. 

However, considering the rapidity at which solar efficiency is rising, and the introduction of tech like the ‘black’ cells, which can capture near-100% of the sunlight, or 3D panels which double or triple conversion rates, similarly powerful plants could become smaller and smaller. 

Anyway, you only need to look at this below image to see that us humans have PLENTY of solar energy at our disposal, we just need to actually use it!
