The IEA alarms that the projected growth of renewable energy power generation must double to meet the objectives set by the Paris Climate Agreement. The inauguration of the Agreement was thought to have a major impact on government policies, renewable energy companies and the public interest, but it did not go as planned. Stock prices of renewable energy companies have risen in recent years, but the academic literature argues that the well-performing stock market is more responsible for the rising stock prices than the Agreement. Time-series analysis is performed to find the true value of five renewable energy technologies by analysing the stock price development of 191 renewable energy companies from 35 countries and comparing them to five individual market indices over an eight-year period between 2013 and 2020. The outcomes are very straightforward, as each individual market outperformed the renewable energy technologies. Wind energy is the clear way forward, solar power needs more attention from non-governments, bioenergy has unclearly defined potential and hydropower and geothermal power need more reliable data to counter their expected decline. The impact of the inauguration was overestimated, and investors were fooled rather than attracted. The energy transition will therefore have to wait a while.
