What is the main problem with renewable energy sources?
Without a doubt, the biggest problem with mainstream renewable energy is intermittency. Wind power is only generated when it’s windy, solar power is only generated when it’s sunny.
Why is renewable energy not good?
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.
What is the biggest barrier to the use of renewable energy?
The most obvious and widely publicized barrier to renewable energy is cost—specifically, capital costs, or the upfront expense of building and installing solar and wind farms.
What is the disadvantage of renewable resources?
One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. … Another disadvantage of renewable energy sources is the reliability of supply.
What are the pros and cons of renewable energy?
Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production. Landfill gas, solid waste energy comes from harnessing the decomposition of organic material.
