A、Coal plants. B、Wind power. C、Hydroelectric plant. D、Solar power. A录音一开头就提到摩洛哥(Morocco)超过一半的能源来自于煤，由此可推测摩洛哥的能源主要靠燃煤的火力发电站(coalp

(22)Morocco gets more than a half of its energy from coal. But as its energy requirements grow, the government is encouraging Moroccans to look for cleaner sources of energy. Morocco needs to find alternative forms of energy to meet its needs, and the best is solar. It’s free energy that is unlimited, available and abundant in Morocco. Morocco’s first solar power plant is being built near the desert gateway city of Ouarzazate. Ouarzazate is an environmentally sustainable city with energy, recycling, land reclamation and water saving resources. It’s also about micro-irrigation, waste water reuse, lighting with solar. It’s a smart city.
     (23)The 770 million project is expected to have the capacity to generate 160 megawatts. The World Bank, the African Development Bank and the European Investment Bank are helping to finance the solar complex built by Saudi Arabia. Officials call the project the largest of its kind in the world, and they say it will be operational next year.
    To raise awareness of the potential of solar energy for Morocco, the oil-scarce country organized its first international solar festival.(24)This festival is organized to show one idea: gold is in the sky. The sun is a treasure for the country.
    Morocco expects to build five new solar plants by 2020 with a combined production capacity of 2 ,000 megawatts at an estimated cost of 9 billion.(25)Officials are hoping to produce enough clean energy to export some of it to nearby Europe.
