Hi, this is Alvaro again. Now, about energy flows, these are the answers: What are the dominant fossil fuels used in your country? The most important and dominant fossil fuels are oil and petrol, and natural gas. Where are the dominant fossil fuels mainly used for in your country? (e.g. transport, industry, non-energy use etc.) These fuels are mainly used for transportation and a wide range of energy uses in urban spaces. It is your task to create a new policy in order to improve the environmental friendly and sustainable sources and consumption of energy of your country. How would you do that? If I was to create a policy about resources and improving the environment, it would be about making all industries related to construction use renewable materiales only. Here the most used material in construction is concrete (95%), and as I learned in the lectures here, it can recycled. Also, I would demand that the enterprises that sell concrete create a mechanism as well to facilitate its recycling. Best regards, Alvaro Note: photo taken from www.constructivo.com
