Critical Reasoning

United Energy recently invested in a series of large windmills which are able to produce renewable energy with minimal negative effect to the environment. The company has not drilled oil wells in the same area, even though greater revenues and profits could be generated from oil wells. Because any drilling would disrupt the native habitat of certain marine species in the area, some environmentalists assert that, by foregoing this drilling, United Energy has established that it places environmental impact over financial returns. However, United Energy may be acting in a manner consistent with its financial goals. Recent patterns of increasing annual hurricane activity have some experts questioning the long-term viability and profitability of oil wells in the area.
