Renewable energy is one hot topic these days, especially as world is trying to make our planet more green and protect it from ever increasing climate change impact. One of the solutions on how to fight against climate change is definitely renewable energy sector that with the proper development can contribute to significant decrease in greenhouse gas emissions. The basic rule is quite simple, the more renewables we use the less fossil fuels we need, and with less burning of fossil fuels there will be less emissions in the end.
But sadly, despite the more than obvious growth in certain renewable energy sectors, overall condition isn’t showing signs of improvement, and world still heavily relies on fossil fuels in order to satisfy its energy demand. Wind and solar energy projects are constantly growing but so do the coal projects, mostly because coal still remains the cheapest fuel, and this is something even developed world finds though to resist, whether alone poor countries of the developing world.
There is also one factor that needs to be mentioned here, namely that fossil fuels lobbies are extremely powerful, and since politics is controlled by industry, they often make their wishes true through trusted politicians. Oil, natural, gas, coal, these are all huge industries, and big bucks involved, and last thing they want is to lose their privileges, and their dominant position in society.
Also, many renewable energy sectors are still not cost effective when compared to fossil fuels, and some renewables have some serious efficiency problems. Higher efficiency, and cost-competitiveness are certainly two major factors that renewables should put their emphasis on if we want to see any significant change in global energy sector in years to come.
