Currently, developed countries are interested in energy issues and energy use. They have a preference for renewable energy. The research and application of renewable energy is becoming more frequent. Wind power, solar power, electric cars, tides are things that are being talked about a lot.
In Germany, there is a road installed with solar panels.
Policies of countries to promote renewable energy. In many developed countries, there is a policy to buy back electricity at a higher price than electricity from fossil energy sources. I believe renewable energy is the future of the world, but we also need to acknowledge the important role of fossil energy such as oil, gas, coal... in the marine industry, metallurgy industry, chemistry...
We are heading in that direction, where the government is promoting the utilization of renewable energy sources. It may not be an easy path, but slowly, people are recognizing the benefits of investing into these renewable energy sources like putting up their own solar panels/wind generator at home. Some countries even have their incentives like in Australia - they called renewable power incentives (not only solar) -
