Traditional power, such as fossil fuels, will make pollution and eventually destroy our environment. In contrast Green Power just uses natural power, for example wind, water and sun can be transferred into energy by various machines to create power. It is more convenient to collect renewable energy because it uses minimal human resources once the machine is installed. On the other hand in mountainous and isolated areas it is more difficult to gain access to the grid. Moreover Green Power needs progressive technology, which means for most people it is unaffordable.
Limited House Purchasing in Shanghai
The policy of the limited house purchase scheme is suitable for big and modern cities, like Shanghai. This is because there are lots of immigrants who buy more houses, which increases house prices. Therefore this policy would control the price and quantity of new houses being built. Moreover, if people do not invest in houses, they will but other products, such as food and clothing, and this can improve the economy. However this policy is not justified for non-local people who really need a house to live in.
