问题如下:

Mike reviews the initiative by Genovia to improve domestic policies and regulations.

The initiative by Genovia is to reduce pollution and promote renewable electricity generation. Two years ago, the government implemented taxes on fossil fuels and subsidies on hydropower and other renewables. Mike reviews the changes in sources of electricity production since the policies were introduced, shown in Exhibit 1.

Based on Exhibit 1, which government policy has been most effective in helping Genovia achieve its initiative?

选项:

A.Tax on fossil fuels

B.Subsidy on hydropower

C.Subsidy on other renewables

解释:

At the end of Year 2, the compound annual growth rate (CAGR) for each sector is calculated as follows: (Year 2/Year 0)^0.5 – 1

Fossil fuels = (426/462)^0.5 – 1 = –4%

Hydropower = (273/186)^0.5 – 1 = 21%

Other renewables = (154/97)^0.5 – 1 = 26%.

The CAGR indicates that the 26% increase in production from the subsidy on other renewables has been more effective than the 4% decrease in production from the tax on fossil fuels or the 21% increase in production from the subsidy on hydropower. Thus, the subsidy on other renewables of 26% is the highest, indicating that this policy has been the most effective in helping Genovia achieve its second initiative.
