The solar source has the greatest generation potential compared to all other sources together, renewable or not. Some estimates claim that if we used the full potential of solar energy on a global scale, it would be possible to generate a percentage of energy two thousand times the total production of all nuclear, thermoelectric, and hydroelectric plants, thus being able to supply our electricity consumption for an entire year.For this and other reasons, most countries around the world are increasingly betting on the use of solar energy, in order to meet their energy demands with a clean and renewable source.Countries like the United States and China are leading the generation of solar energy in the world. In Germany, the goal is to supply 100% of energy consumption through renewable sources by the year 2050.In general, the transition to a clean energy source, transport (electric vehicles) and batteries is a global reality.The 2017 investment numbers in clean energy show that last year was incredibly strong: the value of $333.5 billion, 3% above the previous year’s revised total and 7% from the all-time record set in 2015. Global investment in clean energy in the first six months of 2018 was US$ 138.2 billion, a decrease of only 1% compared to the same period in 2017. Only in the 2nd quarter of 2018 it was registered a year-on-year increase of 8% to $76.7 billion.The rising cost of solar, wind and lithium-ion battery energy mean that market opportunities will continue to open for clean energy, electric vehicles, and storage.Several companies have analyzed the market and predicted that cost-cutting trends will continue in effect in the coming years, thanks to economies of scale and technological improvements – although neither trend is linear, given the importance of balancing supply and demand, commodity and prices.These reductions in solar energy project capital costs. This means that the same sum of billions of dollars will buy more gigawatts than a year ago.
