The document discusses various challenges with different energy resources. Wind and solar power face challenges of not having enough strong winds or sunlight over long periods of time. Managing the turbines and panels would not be difficult. Alternative fuels made from foods may not provide enough power, and collecting the raw materials like corn silk can be challenging. Hydropower provides 10% of the nation's electricity but dams are costly and time-consuming to build. Non-renewable resources like coal, oil and gas will run out, so alternatives need to be found. Managing non-renewables involves controlling pollution emissions and environmental impacts while keeping costs low.
