World Energy Outlook Underestimates Renewables

Ecofys-EU-Wide-Renewable-Energy-Target-Necessary-Part-of-2030-PortfolioThe IEA’s annual World Energy Outlook (WEO) is seen as the most authoritative set of energy scenarios in the world. Yet when we test the forecasts for the growth of renewable energies in the WEO’s main scenario against reality, we find that the WEO consistently comes out too low. Each year from 2006 on the WEO has had to increase its forecast for wind and solar power. Yet each year the WEO predicts the growth of renewables to level off by 2020, for no clear reason. This sends a wrong message to policy makers about the real potential of renewable energy. It is time for the IEA to acknowledge that its assumptions need correcting.

Every year in November, the International Energy Agency publishes its annual World Energy Outlook (WEO). It intends to show the possible directions for our global energy system, with the goal of guiding policy makers in designing their policies and measures. The World Energy Outlook is the most authoritative scenario exercise in the world, and is seen as such by policy and decision makers. It’s not a prediction of the future, but a sketch of possible pathways. The fact that the WEO appears every year makes it possible to assess how well it forecasts the development of renewables in the various scenarios.  Looking back is not a favourite activity of scenario builders – they prefer to look forward. But it is instructive if you want to evaluate how well the scenarios hold up against reality.

As it happens, the IEA has a sub-programme for Renewable Energy Technology Deployment, IEA-RETD, supported by eight IEA country members, which carried out a limited assessment of the WEO-2013 and earlier editions. The results are very interesting. First the good news. In general, the scenarios are of high quality. That is to say, they generally pass the recommendations made in the IEA-RETD’s scenario guidelines (called “RE-Assume”), which were published last summer and which show policy makers how they should understand energy scenarios and transpose their conclusions into policies. The WEO does well by most criteria, e.g. on transparency.

This implies that policy makers should take to heart the WEO’s main conclusion regarding climate change policies: We need to take action that goes much beyond current policies to get anywhere near a safe pathway with respect to energy security and climate change. But the next question for policy makers is: What actions should that be? Here the bad news emerges. The WEO does provide clues about how renewable energy could contribute to the reduction of CO2 emissions, but these clues are absent in the WEO’s main scenario (the “New Policies” scenario). The assumptions about renewable energies used in this scenario and the modelling are based on misconceptions.

Mis-interpreting actual developments

We constructed some graphs showing the cumulative installed capacity of both solar and wind power forecast by the WEO from 2006 to 2013. As shown in the graphs below, every year the WEO adjusted its assumptions upwards. In each year from 2006, the reference scenario in the WEO shows higher cumulative capacity than the year before.

What is more, in all the WEOs the growth is expected to slow down from about the year 2020, but for no obvious reason. Our findings confirm what Terje Osmundsen recently wrote in Energy Post about how solar power is portrayed in the WEO. In wind energy the WEO’s adjustments are quite large as well. Hence, it’s not a wild guess that — unless something fundamentally changes — the 2014 WEO reference scenario will again show an upward adjustment of the growth in renewables towards 2035.

The alternative

The WEO’s New Policies Scenario describes the mainstream developments in global energy. These developments put us on a track for a disastrous global warming of more than 3.5°C, according to the WEO. The globally agreed (but not yet operational) target is an upper limit of 2°C. Hence, the IEA also publishes an ‘alternative’ scenario, which shows what actions should be taken to stay within the 2°C limit. This so-called 450 scenario, named after the upper limit of the CO2 concentration in the atmosphere (450 ppm) that still provides a reasonable chance of staying under a 2°C average temperature increase, is regarded as possible but not very likely to happen. According to our retrospective, especially from 2010 onwards, the alternative, 450 scenarios have been much more representative than the reference scenarios when it comes to the actual development of wind energy (and to a lesser extent, of solar power). As can be seen in the graphs below, the projected growth lines quite accurately follow the actual developments.

Unlike the reference scenario, the 450 scenario shows an increased growth of the cumulative installed wind and solar power capacity, starting from 2020. Obviously nobody knows for sure, but such an upward bend in the graphs seems more what one would expect from energy sources that will have gone further down the learning curve and the cost curve. What we can say, then, is that the WEO in its New Policies scenario in effect treats renewable energy technologies as a ‘black swan’, whereas in reality their development is quite stable and consistent.

Lessons for policy makers

Presenting the New Policies scenarios — including its unrealistic assumptions on renewable energy — as the reference scenario inevitably affects policy makers who will base their measures and policy designs on the WEO. The IEA itself in its policy recommendations does advise policy makers to eliminate fossil fuel subsidies to create a level playing field for renewables. However, in its WEO the IEA seems reluctant to fully explore the realistic opportunities that present themselves in the 450 scenario. It insists on presenting the New Policies scenario as the central one. This makes it seem as if the ability of renewable energy to contribute to lower CO2 emissions is less than it actually is.


Another problem with the WEO’s main scenario is that it insufficiently takes into account the value of things like jobs, environmental damage, health effects, security of supply and household energy bills, all of which are quite important for policy makers. For instance, the negative impact of CO2 emissions on climate-related aspects is expressed in the price of CO2 assumed by the scenarios. The New Policies scenario assumes a price of € 20 per tonne by 2020 and € 40 by 2035. These prices are a lot lower than the actual costs of externalities. This choice directly impacts the relative economic position of renewables compared to fossil fuels in the scenarios. By contrast, the CO2 prices in the 450 scenario (increasing to € 95 per tonne in 2030 and € 125 by 2035) are much more representative of the real externalities. One may argue that including externalities would create an exotic economic basis for the scenario modelling. But to a limited extent, including externalities is actually already happening in real life. New fossil-fuelled and nuclear power plants already are more costly than older ones, mainly because they have to be compliant with higher environmental and safety standards. This can be regarded as a way to prevent part of the external costs mentioned above. Leaving out the full external costs stacks the odds against clean technology.

Realistic policies

Scenarios don’t create their realisation on their own. As the WEO confirms, scenarios can only come to real life with the support of policies and measures.  Policies are absolutely crucial for creating the level playing field for renewable energy sources, including externalities and harvesting the benefits of new energy systems. Nevertheless, modelling a 2°C pathway on realistic assumptions will be instrumental to designing and implementing the right policies. Moreover, if the World Energy Outlook would present a reference pathway that shows larger contributions from renewable energy on realistic grounds, policy makers have the IEA’s authority to rely on when proposing policies. It is time for the WEO to leave this beaten path of describing global mainstream thinking and to provide more realistic perspectives for policies that follow a 2°C pathway. Transposing some of the realism from the 450 scenario to the WEO’s main scenario would re-establish the WEO’s status as a realistic vision and would provide policy makers with a clear view on which sustainable pathways to follow.

Advantages of Solar Energy > Insanity

Advantages of Solar Energy > Insanity

Originally published on Cost of Solar.

The second definition of “insanity” in Google is, “Extreme foolishness or irrationality.” Unfortunately, that definition actually applies to more of what we do and don’t do than we probably want to admit. With extreme insanity, a key thing those of us observing the insanity from the outside tend to notice is that the insane action is done repeatedly. The same insane thing is done over and over and over again, and sometimes the insane person even expects to somehow get a different result despite plenty of experience showing that he or she won’t. It can be quite difficult to watch, and its certainly not a recommended way of life.

You may now be wondering, “What the hell is this guy talking about? Isn’t this site about solar power? Is he insane?” So, let’s get to the solar power part of this.

Want A Livable Planet?


We are actually engaging in very extreme foolishness and irrationality as a society, as we are destroying the climate that makes this world livable for our species (and many others). There aren’t many planets out there that have a climate in which life can exist… actually, we’re yet to find a single one. But we are altering ours in such a way that this highly comfortable climate could disintegrate, so to speak, and become unlivable.

The good news is that we already have the solutions we need to solve this problem. One critical thing we need to do in order to solve this problem is cut the global warming pollution created from producing electricity. And that’s one of the key advantages of solar power. Creating electricity using solar panels doesn’t create any global warming pollution.

One wonderful thing about this solution is that so many of us can participate in this one. Have a roof? Go solar! It would be insane not to.

We have been burning and burning coal and natural gas. We have identified that this is warming our world. And we have identified that this warming could wreak havoc on our civilization, and could even destroy the livability of this planet. And yet, we keep burning and burning coal and natural gas. Insane. It’s time to go solar, and anyone who can do so should really be involved in solving this crisis.

Advantages of solar -- money!

Want More Money?


Unfortunately, the whole “save the planet that we need in order to survive as a species” thing doesn’t seem to have enough power behind it for many of us. Perhaps it’s just too abstract and hard to grasp while the climate is still in fairly good shape. Perhaps it’s just not our priority while we wrestle with other issues. We will just have to face more extreme hurricanes, more extreme droughts and wildfires, more extreme floods, quickly rising food prices, and so on… no big deal.

However, there is one thing that never seems to fail to get our attention — money. And that’s one of the other big advantages of solar power. Right now, almost all electricity is delivered to us from utilities that are nearly monopolies. We don’t have a lot of control over the massive amount of money we send to them. It’s “good” that we send it on a monthly basis, at least — can you imagine if you had to pay it all at the end of the year like with taxes?

But here’s the thing. We get into the habit of sending our money to the electric companies month after month and slowly begin to just stop paying attention to that action. We get into the habit and consider it a normal part of life that we all have to go through. However, all of us don’t have to go through it. Some of us generate our own electricity through solar panels. And many others cut into that bill so much through solar power systems that it frees up tens of thousands of dollars. (Seriously, over $20,000 is the average in the US!)


Average 20-year savings from going solar in US = over $20,000. Over $30,000 in several states, and over $60,000 in Hawaii. (Image Credit: Cost of Solar)

This is one of the big advantages of solar power, and one of the advantages that seems to most influence people to finally break their insane habit of sending money to electric companies (to pollute our world).

And why wouldn’t it? Who would pass up saving tens of thousands of dollars and cutting about 1/3 of their global warming emissions?

Join the US solar power rooftop revolution!

Advantages of Solar Power vs Insanity

In the end, many of us have a fairly simple choice:

Get solar power on our home and/or business, help the planet, and benefit financially.


Continue sending our money to electric companies to make a handsome profit on our insanity while polluting the planet.

Sanity vs insanity. Your choice.
