Sunrun is an United State-based provider of residential solar electricity co-founded in January 2007. It pioneered the use of solar leasing for residential customers and, depending on the applicable state law, offers customers either a lease or a power purchase agreement business model.

As global warming and air pollution continuous to grow these days, It is important for people to use renewable resourses like solar, wind, and nuclear power. As a company, Sunrun provided solar electricity that release zero carbon footprint .  They are response to the environment and contribute to the sustainable developement of  sociaty. For the customer side, they help their costomers to save money on the electricity bill. It seems that Sunrun meets the Corporation Social Responsibility.

However, as we know that firm is a self-contained, profit maximizing entity. Many people argue that the purpose of companies like Sunrun is only to earn more money. Government has a 30% federal tax credit for residential solar electricity projects, and the leasing companies are able to sell their tax credits via a tax equity fund. These people said that the government is wasting the tax payer’s money. For me, I think that profit maximizing and social responsibility can coexist. And the solar electric companies will works better and better that at last, they will be able to get off subsidies.
