What do you think about green energy?

I consider that this issue is to be very important for all countries (all countries implies the world) in the world. The solution is very complex because there are many financial along with and technical factors that influenced this issue. My main idea would be is that the government needs to invest more money in research and development. The Technology is the main activity that the what countries need to figure out this problem out, so the problem depends on the state of the economy. Nowadays, countries such us (say your country not us) China, Germany, US, and many others have designated many resources to research new solution in order to find out the solutions for these problems. The following questions is are; "What will happen with to the other countries?", "What will happen with to poor countries or developing countries?" and "Where the government destined your budget to another aspects (I'm not sure what you are trying to say in this last question. If you rewrite it I will make corrections to your new question)." 
Green energy needs a lot of research. There are many prototypes that should be proved and validated (proved=validated) in order to get the right knowledge about understand the design. Some technologies are not mature, and mainly it which could causes (cause is singular here) many technical problems to for the electrical power system. This problem will be seen in the future, because only a few places have reserves. Therefore, we need alternative technologies to supply the future consumption of the customers consumers. For these reasons people can will realize that this issue is crucial nowadays. It There is not no easy give a final solution, but I consider that green energy is to be very important. The power systems needs need (singular) that private companies will to invest in these kinds of technologies. These investments could increase our tariffs, but the industry needs the energy to improve the economy in of each country. Finally, each country has different aspects and of developing development, so it is the time to change our behavior. and maybe One day scientists could may be able to find out new technologies for to better our future. We need money to do it make this happen due to the because energy is crucial in the economy.

*You did very well in this entry. Don't try to use too many words especially with scientific papers. Be clear and concise with what you are trying to say and watch out for run on sentences. Your only other issue is when to use which preposition, so be very mindful of what you are writing. Great job overall, your vocabulary is very broad and you know when it is appropriate to use which word. You are definitely advanced in your English skills.
