Climate change did not become talked about until the late 1980's. Even though a few scientists like Svante Arrhenius of Sweden tried to raise the alarm of the global impact of fossil fuels one hundred years before in the 1890's. It wasn't until around 1958 when the measurements of carbon dioxide confirmed Arrhenius's views that many others discredited before, these greenhouse gases did in fact warm our climate. The global temperature began to rise at an unprecedented rate in the 1980's bringing new cause for alarm in the scientific community and finally among the media and general public. Since then the goal to switch to more renewable energy resources has begun. This map from solarpower.guide shows that in the US, solar, wind, biogas, geothermal and hydro have emerged as leaders in clean energy resources. The government has many incentives for entities who make the switch to using renewable resources. Below are the top 20 government entities in the US that run on the most renewable resources:
