Why geothermal energy sources may not always be truly sustainable?
On the negative side, geothermal sources may not always be truly sustainable. If a geothermal power plant uses heated water more quickly than groundwater is replaced, the plant will eventually run out of water. In addition, the water of many hot springs contains chemicals that dam- age equipment and add to pollution.
What is one problem with using renewable energy?
It Still Generates Pollution Many renewable energy forms or their manufacturing processes emit greenhouse gases like particulates into the air, carbon dioxide, or worse – methane. It is partly because the resources needed for renewables are built using fossil fuels.
Why sustainable energy is bad?
Although renewable energy sources produce relatively low levels of GHG emissions and conventional air pollution, manufacturing and transporting them will produce some emissions and pollutants. The production of some photovoltaic (PV) cells, for instance, generates toxic substances that may contaminate water resources.
Why geothermal energy is not renewable?
It is not a nonrenewable source of energy because it can be re-used without being truly depleted! Geothermal energy is a renewable energy source because it generates unlimited thermal power from the Earth’s core. Geothermal produces electricity without depletion, so it is not a nonrenewable energy source.
What are the pros and cons of biomass energy?
No energy source is perfect, biomass included. Though it is renewable, there are both benefits and downsides to generating electricity using biomass energy plants….Pros and cons of biomass.
| Pros of biomass | Cons of biomass |
|---|---|
| Renewable | High costs |
| Waste reduction | Space requirements |
| Reliability | Some adverse environmental impact |
