I'm enlightened by the real problems and the key points mentioned in the additional reading.

As the clean energy plays a key role in facilitating the situation of the environment, either governments or private sectors should continue to use it as a powerful tool. However, with the subsidy system, the price of electricity is dragged down in response to the increasing competitiveness of the clean energy. The consumers seem to benefit from this. But from the investors' view, it produces more good if they put their money to the electricity industry in an effet to pocket from it. Why? Because renewables' running costs are nearly zero, there's no money to make so why do the investors keep wasting their money just for the long run? That's the situation for companies.

So people are expecting the support from the governments. What they should realize is that policy makers' first job is to boost the economy and stipulate proper policies to create revenues. As a result, they have to consider the short-term restraints. So they put brakes on developing renewables, making renewables' future a problem.

There's a vicious circle, a death spiral that we wouldn't be able to get through if we don't make any breakthoughs in terms of technologies and policies. Luckily, as the article points out, the new technologies are discovered such as digitalisation, metering and batteries. And the root of the problems is pointed by the analyst, which is to redesign the electricity pricing system. A final balance can be made between the renewables and the electricity, as there's a impossiblity that countries, all over the world, could all only depend on the renewables like solar and wind. The joint efforts need  to be made to solve the problems.
