Renewable energy development is an important alternative to the conventional energy sources. While this issue has been taken seriously, government plays a substantial role. By comparing government’s output of wind and solar power development in this infant industry from the Germany, China and USA as leading countries in this field, we can see the different degree of government intervention among those three countries. Regarding to this approach, it will allow us to understand whether state-aid more successful than market-oriented or not.

使用再生能源替代傳統能源是一項非常重要的發展。在社會大眾普遍重視再生能源議題的背景下，政府扮演著非常重要的角色。藉由比較德國、中國以及美國這幾個領導性國家，來觀察在政府的參與下，風力發電與太陽能此兩項嶄新產業的發展。如此一來，我們可以明顯看出這三個國家各別政府在不同程度上的介入下所產生的影響。根據此項方法，我們可以清楚了解再生能源的發展是否應該強調政府的介入為主還是市場導向為主。
