We know that the coal we have is finite. It's going to run out some day. It makes sense to look for energy sources that will last longer and cause less harm to the environment in the process. Smog filled air isn't healthy and no one likes to live in it. So, yes, all countries should invest in renewable resources for the benefit of their people.
Renewable resources are the future, and expanding the potential of this exciting development should absolutely be pursued. However, let's not go so far as to give Beijing credit for pushing the discourse in this regard. Many Western countries - the United States, the United Kingdom, and Germany, among others - have already been pushing the global discourse in this directions for years.
Yes, all countries should invest more in renewable resources. They are the next great need in infrastructure. People like to look at roads and bridges as needed infrastructure, but our energy resources also need to be shored up. An over-reliance on nonrenewable energy sources such as oil is going to lead us into trouble in the not-so-distant future. It's time to fix that problem.
All countries should not follow in China's footsteps and invest in more renewable resources unless it benefits those countries. As of now, the renewable resource issue is one that seems a fine and dandy, but the reality is that the overall effects are often counter-productive. In fact, in many instances such schemes cost a lot more to implement than the benefits returned. It's simple economics.
