The ish
Two renewable but exhaustible resources
Answers
Answer:
air and water is correct answer
Explanation:
A shift in the global energy supply is crucial to combating human climate impact. Large quantities of renewable energy technologies, such as solar cells and wind power, must be deployed globally to replace today's fossil-dominated energy supply. Solar and wind energy are growing rapidly, but while the energy is renewable every solar panel and wind turbine is largely made from non-renewable resources. These energy technologies also have a limited lifespan and the power plants we build today will need replacing in the future.
The thesis "Natural resources and sustainable energy," which is the first thesis in the new field of doctoral education 'Natural resources and sustainable development' at the Department of Earth Sciences, studies the industries and natural resource flows necessary for a continued rapid expansion of renewable energy. It also discusses how these technologies are to be replaced when they reach their end-of-life.
"Renewable energy technology can lead to reduced emission of greenhouse gases, but for a complete analysis we need to make sure the whole production chain is sustainable. For instance, it is not obvious that the production of wind turbines and solar cells is sustainable, that the materials have been sourced in a sustainable way, or that the industries are capable of recycling the technology in the future," says Simon Davidsson, new PhD at Uppsala University
