what are the two most important drawbacks of renewable energy?

Unreliable weather can affect energy supply. As renewable energy often relies on certain weather conditions, this can impact the reliability of a constant energy supply. For example: Hydro generators need enough rain to fill dams for their supply of flowing water. Wind turbines need wind to turn their blades.

Coal power plants and burning fossil fuels to generate steam power also has a more negative impact on the environment that concentrated solar power. ... The aggregate environmental impact of steam power is far worse than other sources of energy such as solar, wind, and hydro.

Hydropower has the ability to generate electricity without emitting greenhouse gasses, however, it can also cause environmental and social threats, such as damaged wildlife habitat and harmed water quality. Hydropower is the most important and widely-used renewable source of energy.

Benefits of Renewable Energy Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels. Creating economic development and jobs in manufacturing, installation, and more.

Disadvantages of offshore wind: The biggest disadvantage of an offshore wind farm is the cost. Onshore wind farms can be expensive to build and maintain and because of their hard to reach locations, they are susceptible to damage from very high-speed winds during storms or hurricanes which is expensive to repair.

In fact, there's only one notable disadvantage to solar power that I can think of. That disadvantage is that the sun doesn't shine 24 hours a day. When the sun goes down or is heavily shaded, solar PV panels stop producing electricity. If we need electricity at that time, we have to get it from some other source.

Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat.

Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste.

Renewable energy provides reliable power supplies and fuel diversification, which enhance energy security, lower risk of fuel spills, and reduce the need for imported fuels. Renewable energy also helps conserve the nation's natural resources.

['The main advantages of non-renewable energies is that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles.', 'Non-renewable energy is cost effective and easier to product and use.']

On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them.
