Is solar energy considered sustainable?
Sustainable energy is derived from resources that can maintain current operations without jeopardizing the energy needs or climate of future generations. The most popular sources of sustainable energy, including wind, solar and hydropower, are also renewable.
How does solar energy promote sustainability?
Solar energy does not emit toxic substances or contaminants into the air, which can be very damaging to the environment and to human beings. … Unlike fossil fuels and nuclear power plants, wind energy has one of the lowest water-consumption footprints, which makes it a key for conserving hydrological resources.
Is solar energy actually good for the environment?
Solar energy systems/power plants do not produce air pollution or greenhouse gases. Using solar energy can have a positive, indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment.
Why is renewable energy unsustainable?
The reason why these energy sources are considered unsustainable is that there is only a finite supply. Technically, these energy sources can replenish themselves, but it can take millions of years to do so. Therefore, they cannot be considered renewable for energy production with the number of resources we demand 2.
