How Much Renewable Energy, and When...


 I pulled this from Zach Strahan's 'Clean Technica' blog.  As he points out, there is a wide range of projections on how much clean energy we will have in the future.  It really comes down to who is making the projections. Those who stand to gain from minimizing the estimates, like big oil,  see themselves as still being important players in the energy arena in 2030 and beyond.  That's because they control our government's energy policy. If the public demands a rapid transition to clean technologies, it can happen. The technologies are already here.

How Much Renewable Energy Will Be Installed In 2030? 2040? 2050?


 
Ren21 — a global renewable energy policy multi-stakeholder network that connects governmental bodies, nonprofit organizations, industry associations, research institutes and universities, and members of civil society — recently conducted a massive, 75-page report on a large variety of potential renewable energy scenarios for the coming decades. The report, “REN21 Renewables Global Futures Report,” compares scenarios created by fossil fuel companies (like ExxonMobil and BP), leading nonprofit organizations (like Greenpeace and WWF), the International Energy Agency (IEA), and others. In total, Ren21 reviewed 51 different scenarios.

The report is very detailed, so it’s worth a close read by anyone who is very interested in the topic of renewable energy, or who is working in a relevant industry. But even for the common citizen, I think there are some key points to pull out of it (and of course some fund charts and graphs).
First of all, the key point is that there are massive differences between different scenarios or projections. As one would expect, those who benefit financially from keeping things closer to how they are right now (i.e. BP and ExxonMobil) created scenarios that projected much more limited renewable energy growth, while environmental organizations (i.e. Greenpeace and WWF) created scenarios that projected much more optimistic renewable energy growth.

I think there are generally two key, overarching points to take away from the variety of scenarios:
  1. Policy choices have a humungous effect on what sort of world we create in the coming decades. Policy factors were the only assumptions that resulted in the scenario variations. Of course, there were many assumptions used in each study that had an effect on the results — technology advancements, consumer behavior, industry behavior, etc. But policy assumptions were one of the most important — probably the most important. And policy choices are up to us. They are up to citizens, and of course legislators.
  2. Scenario projections themselves are used to influence policy and the public. It may seem obvious, but it’s worth pointing out that the scenarios put out by BP, ExxonMobil, WWF, Greenpeace, etc., while they are simply based on different assumptions, are often aimed at influencing what the public and policymakers think can be done, should be done, or even will be done. They are tools used to advance certain goals.
With those two points in mind, I would just emphasize that the future is ours to make, and we should make it a clean and safe one.

Global warming and climate change pose a huge threat to human civilization and the human species, as well as countless other species. We could cook ourselves out of existence. Rather than do so, we can demand policies that will protect our climate (while also cleaning our air and water, creating jobs, improving our economy, and making our lives more convenient), or we can sit on our butts and let big fossil fuel companies control our governmental bodies in order to maximize their profits (at the expense of society as a whole).

The choice seems obvious, which is why I do what I do, but it’s clear that we need more people to share this sort of information, get involved in industries improving the world, and get involved in politics in a way that will also help lead us to the more logical future.
OK, that’s all I have as far as text goes. Here are some more charts, images, and tables from the report for your enjoyment and use:
