Earlier this month, the International Renewable Energy Agency said the world needed to invest $131 trillion by 2050 in order to limit the estimated global rise in average temperatures to 1.5 degrees Celsius. That’s 30 percent more than what is currently planned. It’s also equal to investments of $4.4 trillion every year from now until 2050. How realistic are these spending goals?
Well, it appears that the realism of IRENA’s estimates depends on how you look at the energy transition: as simply an increase in renewable energy generating capacity and a consequent increase in the share of electricity in national energy mixes. While not exactly wrong, this widely shared perspective fails to account for the sheer scale of the change we are in the process of undertaking.
James Bradford, chief executive of asset manager Vivid Capital management, compared the energy transition to the Industrial Age in terms of significance—an era that will present substantial challenges and numerous opportunities.
“There will be some spectacular growth industries developed along the way,” Bradford told Oilprice. “Installed solar capacity for example is expected to grow from less than 1TW today to nearly 10TW by 2050. That’s 10x growth, which is enormous growth, for any industry.”
And solar is just one example. When you add all the other renewable forms of energy such as wind or biomass, or hydro, and the ambitious plans many governments have about hydrogen, the scale of the transition—and the fitting size of the investment needed to implement it—becomes more obvious.

Have investors lost interest in “clean energy”?
A year ago, using data from Bloomberg New Energy Finance (BNEF), I put up a post discussing global “clean energy” investment between 1Q 2005 and 2Q 2017. BNEF has now published a new report adding a year of data through 2Q 2018 along with some more detailed graphics. This post reproduces some of the more interesting ones, with an emphasis on Europe.
First we will deal with the question of the inadequacy of clean energy funding. According to the BP Statistical Review global electricity demand in 2017 was 621 TWh higher than in 2016, an increase of 2.5%. Table 1 shows how this added demand was filled:
*Wind, solar, geothermal, biomass, waste, biofuels etc.
To decarbonize the world’s electricity sector and to meet emissions targets enough renewable generation must be added each year a) to cover increased global demand and b) to replace a significant amount of fossil fuel generation. Table 1, however, shows that the 307 TWh of renewable generation added in 2017 was enough to fill only about half of the increase in global demand.
