<human>:  What are the pros and cons of different energy sources?
<bot>: 
Pros of different energy sources:
 • Renewable sources like solar, wind and hydropower emit no greenhouse gases and have a much lower environmental impact than non-renewable sources.
 • Renewable energy sources are reliable and cost-effective as they can be used to generate electricity and to meet our increasing energy demands.
 • Renewable energy sources are also relatively easy to set up and maintain, and can provide an influx of employment opportunities in rural and remote areas. 2

Cons of different energy sources:
 • Renewable sources of energy can be intermittent, depending on weather conditions, so they need to be supplemented with other sources of power when the sun isn't shining or the wind isn't blowing.
 • Renewable sources of energy can also require large areas of land or expansive stretches of coastline in order to be fully effective, so they can be quite disruptive to local ecosystems and habitats.
 • Non-renewable sources of energy, like fossil fuels, are often cheaper in the short-term even though they are more harmful for the environment in the long-term.
