4)Why are solar energy and wind considered potential resources?
Answers
Answer:
because they are not used much now but have the potential of providing great benefit in the future if used.
Answer:
India became the world's third largest producer of electricity in the year 2013 and accounts for 4.8% of global share in electricity generation. But its per capita electricity consumption is only 746 kWh, which is lower compared to many countries, though electricity tariff is cheaper in India.
Explanation:
The most sustainable energy sources are renewable bioenergy (wood, biomass, energy crops), geothermal (deep or shallow), solar energy (photovoltaic, solar thermal), hydro and wind energy. Since much more, orders of magnitudes more, solar energy hits the earth than is required for human needs, the total potential of renewable energies seems to be almost infinite. It should be noted that, with respect to our discussion about energy here, the term "potential" is not the same as in physics (see Mechanical Energy). A better term would be "availability". Also, the terms "renewable energy" and "energy sources" do not make sense physically, since in physics the energy conservation law prohibits a source or renewal of energy; only transformations are allowed. From a physical point of view, it would be better to formulate this as "availability of sustainable energies" instead of "potential of renewable energies".
