There does appear to be an appetite for a change, evidenced by last year's historic agreement at the COP21 summit in Paris.
There, world leaders agreed to make sure global warming stayed "well below" 2 degrees Celsius and to "pursue efforts" to limit the temperature rise to 1.5 degrees Celsius.
"If the world is serious about tackling climate change, the world's energy mix in 2050 will have to look fundamentally different from the one we have today," Gunnar Luderer, from the Potsdam Institute for Climate Impact Research (PIK), told CNBC via email.
"Limiting global warming to well below 2°C, as agreed by the international community at the climate summit in Paris last year, requires close to carbon-free electricity supply and a drastic reduction of fossil fuel use in the industry, transportation and buildings sectors," Luderer added.
Bearing all of the above in mind, solar looks set to have a very big role to play in the world's energy mix.
In 2014, the International Energy Agency stated that the sun could be the planet's biggest source of electricity by 2050.
"With the emergence of renewable energy technologies as the top sources of new power for the United States, we've entered a new paradigm that's here to stay," Tom Kimbis, interim president of the Solar Energy Industries Association (SEIA), told CNBC via email. "Solar is at the heart of this revolution," he added.
"Innovative, high-tech and inexpensive, solar is a disruptive force whose growth (has) been highly unsettling (to) entrenched energy producers. It's not a question of if solar will power our economy -- nor a question of when -- but how quickly."
Other renewables are also pushing hard for a bigger slice of the energy pie. Wind energy is one such source. According to WindEurope, the offshore wind industry in Europe saw 14 billion euros ($15.67 billion) in new investments in the first six months of 2016.
"With the great leaps that wind energy has made in cost reduction in recent years, there is no reason why it should not be the centerpiece of energy systems around the world, particularly Europe," Oliver Joy, spokesperson for WindEurope, told CNBC via email. "Wind keeps getting cheaper," Joy added.
"Costs for onshore wind are expected to fall by 41 percent by 2040 as larger turbines with higher energy capture make the economics even more attractive. Offshore wind is also rapidly moving down the cost curve."
Joy went on to add that wind energy was able to meet 12 percent of Europe's electricity demand, with WindEurope seeing that figure rising to 28 percent of demand by 2030, provided the right policy decisions were made.
For the PIK's Gunnar Lederer, "the resource potential for solar and wind is vast."
