Why Germany Should Show Off It’s Dominant Renewable Economy

Germany’s renewable share for the first half of 2012 has recently been released, and guess what, they’re thrashing the majority of EU nations comfortably, reaching 26% overall, a staggering increase from 20.5% during the same period last year. That means that over a quarter of the energy filling the German grid was produced purely by renewable means, and that is something they should be seriously proud of, and rubbing in our faces, as I’ll explain below.

What is even more interesting about this event, is the specific mix of renewables used in accomplishing this task. Wind sits in gold medal position with 9.2%, with biomass (surprisingly) taking second with 5.7%, whilst solar PV follows closely behind with 5.3%, expanding by over 40% in comparison to last year. That alone is an impressive stat to contend with, and was no doubt bolstered by Germany’s generous FiT, which although was recently slashed to save on funding, has been highly successful in generating consumer interest in solar as a viable energy alternative.

Hydropower boosted 25%, up to 4% in the overall mix, with all other renewables completing the lineup.

It’s no surprise that wind energy takes pole on the list given how perfectly flat, large and windy Germany as a landscape is, and their heavy involvement with the cheapest of all renewable technologies. Many have attributed the extra-impressive results to the weather this region of Europe has been experiencing over the past 6 months, with abnormally high winds spinning up the turbines country-wide, torrential rains over-powering the hydroelectric dams, and in the later parts of the year, intense solar radiations and clear skies bathing the abundant solar panels in beaming energy.

Then again, attempting to diminish the feats achieved by the German renewable grid by stating it ‘was the weather which made it so damn good’ is a tad cheeky, considering the very point of many clean energy sources is that the sun and weather itself drives the production. If we have optimal weather, then they’re working exactly as planned.

What was surprising is the biomass share, which was much more than I thought had been invested in, with this form of energy generally not so high on a country’s energy list. I’m assuming that good recycling programs and clever biomass burning policies mean that Germany’s energy production is relatively high here, although actual year-on-year growth has been the smallest in this sector, just 7.5%.

It’s Time To Wake Up & Smell The Renewable Revolution, Soon We Won’t Have Any Other Choice

|#

As a global society, we currently stand on a precipice; the potential catastrophe that awaits us cannot be downplayed in any way. Brought about by fossil fuel greed, mass shortsightedness and a complete and frankly terrifyingly impressive ability to ignore all signs of danger and wrongdoing for decades past, humanity has ravaged the planet to a point where civilisation is at the fork in the road.

Unless we make a change, a global change, we begin the short walk down one road towards an extinction level event, bigger than any nature has wrought upon life before us, that will be impossible to turn back from. Forgive my foreboding and perhaps depressing approach, but I for one see only one route out of this. For centuries before now, humanity has prided itself on its ability to innovate and outsmart our way out of danger, and never more than now is it crucial we do this once again.

It’s with these thoughts ringing heavily in my ears, that I turn to what I feel are some of the most frustrating and dismissive problems large majorities of society have with certain renewable technologies, as well as some of those dirtier fossil fuels such as natural gas, which despite being part of the problem, are rapidly taking precedence as the answer to our carbon woes, a fantastic alternative to that old demon oil and coal.

Unfortunately I do not foster the same feelings towards natural gas, and also do not tend to follow suit in regards to issues with solar panels, wind farms or nuclear plants, all of which are the truly awe-inspiring innovations with which we can slow, stop and eventually reverse the once irreversible damage we have wrought upon this beautiful planet. As you will hopefully see in the following summaries, many of the so-called ‘negatives’ with each of these technologies, is in my eyes, and I’m sure the eyes of many others, both ridiculous and detrimental to society as a whole, a statement I do not wish to undervalue in this post.

Let’s get straight to the major players, solar and wind. The one complaint about these two absolutely wonderful technologies is one that angers me greatly - “they’re too ugly, don’t go putting them on my roof/in my garden/anywhere within a 50 miles radius or my house”. Apologies if you’re someone who shares these feelings, but I simply cannot agree with such a weak and destructive view when you consider the grand scheme. As job creators, solar and wind each produce at least 6x the number of jobs that coal and oil do, with a much larger percentage in long term maintenance, a highly secure career. Not only this, but subsidies, feed-in-tariffs and government funding has aided these industries in literally exploding in value and popularity, and lest not forget, solar and wind are entirely clean, completely renewable and have the potential to provide huge proportions of the world’s energy.

Fukushima All Down To Human Error, Not Nature’s Wrath

|#

http://02varvara.wordpress.com/2011/03/29/a-photo-essay-two-weeks-after-the-japanese-tsunami-the-russian-report/04j-tsunami-two-weeks-later-29-03-11-fukushima-npp-fukushima-prefecture-tohoku-region/

With Japan turning on the first of potentially many nuclear reactors shut down in the wake of the horrendous Fukushima disaster, the entire ordeal has come round full-swing and back under public scrutiny once again. Many of the Japanese public have rallied against this switching back on, of what is deemed as crucial supplies of electricity with the coming warm summer, and the whole country has been experiencing protests and demonstrations the likes of which are rarely, if ever, seen within the kooky nation.

Unfortunately, the flipping of the nuclear switch could not have come at a worse time in terms of global public opinion, with the release of the final report from the Japanese government pertaining to why and how Fukushima came to not only lose all power including backup, but to explode in quite an impressive fashion, spraying the surrounding landscape with nuclear fallout, albeit resulting in no deaths or serious injury, at least up until now. The conclusion of the investigation was brutal and to the point - nature was not to blame, but poor regulation, collusion between multiple governing bodies, safety issues and a complete lack of any effort to solidify the plant against possible disasters. In short, it was manmade.

(http://www.treehugger.com/energy-disasters/fukushima-disaster-declared-manmade-final-report.html)

Going further, the report finds that since 2006, the plant executives and safety managers knew full-well that a large tsunami had the potential to severely damage the plant and shutdown the seawater pumps which lead to the hydrogen release and explosion. When the disaster struck, they were “quick to blame the tsunami and that further investigation into the earthquake impact was needed”.

In the end, it was seen that a lack of care for public welfare and an apparent focus on mitigating risk to the organisations involved ultimately led to poor handling of the situation both before and after the incident, with safety protocol and radiation measures all but ignored in the proceeding weeks. So all in all, it was a haymaker to the face of all those governing bodies tasked with dealing with Fukushima, and any talk of nature being the prime suspect were all but swept under the rug in an instant. Silly, naughty Japanese government.

Personally, I feel this report, of which I’m sure was extremely professionally handled and undoubtedly raises some serious questions over safety and nuclear regulation worldwide, still takes the issues far too deeply into the human end of things. Yes, safety measures were weak and outdated with little likelihood of being updated, and the ridiculous amount of dotted lines and red tape the nuclear fission process has to go through almost certainly leads some to cut corners, but there are other issues afoot.

When the earthquake struck, it was far beyond even the most extreme projections the Japanese officials had tested, hitting a whopping 9.0 on the Richter Scale, making it not only in the top five world’s largest quakes, but the largest Japan has ever recorded. Combine this with the shallow depth at which it struck, just 20 miles below sea level and only 43 miles off the coast, and the tsunami produced reached heights only Hollywood movies could conceive. In effect, it was a perfect storm of natural disasters.

Japan Sets A Risky New Bar In Solar Tariffs: Too Risky?

|#

Ater what seemed like a potentially tumultuous time for Japan once the final nuclear reactor was shutdown just months ago, it seems the fledgling nuclear industry may once again be getting a restart, after conformation from the Japanese government to go ahead with the reopening of two reactors in the near future. Considering the fallout from Fukushima and intense protestation from the Japanese citizens towards any sign of rekindling the nuclear fire this is an important step forward in the debate.

It couldn’t come at a better time, as current supplies of fossil fuel based energy has been ramped up to over 90% from 60% before the shutdown to deal with the increased strain on the country, which of course leads to higher emissions and a greater risk to society as a whole, a reaction I figured would be the case from the moment of hearing about the nationwide closures. Coming into the hot Japanese summer was no doubt a primary factor in determining the restart of both plants, as an overuse of A/C and the need for cooling would have likely overloaded the grid periodically - not something a leading 1st world nation wants to be fronting during such critical times.

What is even more reassuring however is the news of a brand new feed in tariff directed towards Japanese renewable energy, with solar in particular, a sector which is booming globally, and set to really explode in Japan if given the right treatment, ala Germany or the UK. Whilst these FiTs are common ground to those who follow the solar debate, the Japanese have taken what is in my view an extremely risky and brash angle, which could bring them closer towards a solar dominated grid with popularity through the roof, or complete economic slump and a positive drive away from renewables as it stands.

They’ve done this choosing to set their price per KWh at a staggering $0.53, which is triple that of China’s and double the current UK rate, which is set to fall over the coming months. Through this astounding figure, which translates to how much money a consumer will be paid per unit of solar energy they produce, Japan hopes to blow all other solar markets out of the water, installing up to 20GW of solar alone by 2016.

This tariff also applies to wind, geothermal, biomass and more, all of which Japan is seemingly rushing into as the global markets pick up pace and fossil fuel support falls all around. Even wind FiTs beat German prices, currently some of the best in the world, and many of these tariffs guarantee set prices for 20 years, a much more ambitious projection than all other renewable European nations.

Personally I believe this is wonderful news to the highest degree, and to see a country which only recently shut its entire nuclear capacity down, an energy source to the tune of 30% of nationwide production, to then rapidly put in place such radical policies to promote renewables is signs of good things ahead. When many other countries are blaming a lack of solar, wind and biomass on a lack of space, unfavourable conditions and poor public support, Japan is flying in the face of such issues; the nation is comparably small, highly mountainous, densely populated and a world leader in technology and economics, and they plough on like never before. Many nations should take note and learn, as Japan could be the next big green player.

However, before I get too excited and jump the gun, I would like to point out some potential problems, some of which could really derail this phenomenal move. Both of the big leaders in solar FiTs, Germany and the UK have both experienced the results of highly attractive and lucrative tariffs, set too high for the nations coffers to fund once installations shot up dramatically. Due to this, both have been forced to slash prices and guarantees in the face of public protest, in attempts to be able to continue paying the consumers who so gleefully latched onto the policy.

Now we see Japan setting prices at double the market rate, with 20 year warranties; is this not setting itself up for a huge fall if they calculated wrong and cannot continue funding the explosive growth as many analysts expect? Germany and the UK thought they had it sorted, and even though their sectors are still growing, solar installations have taken a wounding blow, one which will continue to bleed for a whole longer before the market reasserts itself.

If Japan doesn’t manage to control these tariffs, we could see problems in the solar market which could deliver a potentially fatal blow to FiT schemes around the world. When you’re dealing with such a fickle public as ourselves, the knowledge that two or three schemes failed to deliver their original promises could mean the end for something which is only just finding its feet.

NREL's Renewable Energy Map Takes Mapping To A New Level

1 note |#

The National Renewable Energy Laboratory’s fantastic customisable map, demonstrating every conceivable form of green energy you can think of, really sets the bar high for future mapping of this kind.

Head on over to the link above and you’ll find yourself presented by a US-wide map with a multitude of drop-down settings to choose from, ranging from solar (PV & concentrated) to biomass, with a ton of information buried further in the tool. Each selection layers the map with the chosen resource/s with a neat coloured scale, gradated in an easy way to understand.

It’s the ease of use that really shines with this beast, as in a matter of minutes you can select wind or solar, see the data sources in detail, before bringing up a beautiful list of features, such as estimated solar radiation figures or wind class, all of which can be done at a localised scale; there is even a ‘find location’ button to type in a specific address.

With such user-friendly tools like this available to both the public and professionals, it is maddeningly easy to see that the world has plenty of renewable power for us greedy humans, and hopefully more global maps will follow suit soon.

For the moment, check it out and enjoy, it’s well worth it.

Japan To Burn Tsunami Debris For Energy And More

|#

Japan is set to make some big steps into the renewable industry from July onwards, with it’s ventures into multiple sources of clean energy production and low-carbon technology. This is a key development after the closure of every single nuclear reactor come May, once providing roughly 1/4 of the country’s energy needs.

First on the table is a brand new solar FiT (feed-in-tariff), which will hope to incentivise and fund companies and customers desperate for a bit of sunlight-energy in their lives, and will aim to work in much the same way the German and UK FiTs functioned, until the cuts obviously. A major difference however, is that this tariff will force utility companies to purchase electricity from clean sources at predetermined prices, and this will have to be passed down to the customer, in the form of a slightly fatter bill through the letterbox.

This is one of the primary hurdles which must be jumped in order to put this tariff into place, as many ministers and analysts will struggle to pin down an appropriate price which can be nationally distributed without anger and reprisal from the public. On the other hand, the Japanese are known for their obedience and rational thinking in situations like this, and so I feel that once a price is set, both utilities and customers will work together to make the FiT work efficiently.

Various projects are in the planning and finance stages, ranging from a whopping 340MW plant in Hokkaido, to a 70MW construction which will stretch out across part of Kagoshima Bay and all it’s shiny glory. Many other smaller projects round the proposed sum up at almost 0.5GW of solar energy.
