Why Do We Need Renewable Energy, & Why Should We Use It?

Renewable energy is increasingly seen as one of the pillars of a sustainable society and world.

But, why exactly do we need renewable energy, and why should we use it?

… We’ve looked to provide answers to those questions in this guide.

Additionally, we’ve also outlined some reasons we might not need renewable energy and why we might not use it.


Summary – Why We Need, & Why We Should Use Renewable Energy

We might need to use renewable energy for a range of reasons, with some of the most important being that it perhaps won’t deplete as we continue to use it like fossil fuels might, and also, it’s probably more environmentally friendly than fossil fuels (although interestingly, there have been some reports that countries like Germany will require the unsustainable use of raw materials, as well as fossil fuels to build new equipment such as solar panels and wind turbines for their renewable energy transition)

We might not use or need renewable energy in the short term for a range of reasons including initial/upfront costs, variability/intermittency, lack of natural resources potential in a given country or region, and other reasons

Based on all the pros and cons of renewable energy compared to fossil fuels and nuclear energy, it certainly seems like renewable energy is a wise decision to use to address incredibly important issues like climate change, air pollution, and depletion of natural resources over the short, medium and long term.

It can help start addressing some issues immediately, but also help address some issues on a longer term scale

Some people outline the use of renewable energy (for electricity and eventually transport and heating), and sequestration or carbon farming of carbon dioxide, as the two most important solutions we have to keeping global warming below certain temperatures in the future

Overall, renewable energy may be used in different amounts in different countries, States and regions around the world in their energy mixes and electricity systems – and, individual assessments and decisions should be made for each of these locations (as they all have different variables, factors, challenges and considerations at play).

All the economic, social and environmental pros and cons should be weighed up for the short, medium and long term, and a decision should be made to progress with, or hold off on renewable energy based on these pros and cons.

Obviously, if the short term cons of transitioning to renewables are significant, then it should be transparent how renewables are beneficial in the medium to long term to justify these costs.


Why Do We Need Renewable Energy, & Why Should We Use It?

We already put together a few guides that answers this pretty well:

Why Is Renewable Energy Good, & Bad?

The Importance Of Renewable Energy, & The Benefits & Advantages (Environmental, Social, Health & Economic)


In these guides, we mention how renewable energy is a sustainable energy source, and has environmental, economic, social and health benefits.

It might be surprising to some how many potential economic benefits like job creation that renewable energy might have in the future.

Environmentally, addressing climate change (because renewables tend to emit less carbon dioxide and greenhouse gases), and air pollution (because renewables tend not to emit air contaminants that dilute air quality) are important considerations.

Socially and health wise, renewables can help address the health issues and costs related to air pollution.


Why Don’t We Need Renewable Energy, & Why Shouldn’t We Use It?

It’s not necessarily that we don’t need or shouldn’t use renewable energy, but there can be barriers with transition to any share of renewable energy in a given energy mix.

We’ve put together several guides that outline the problems and challenges with moving towards renewable energy:

Challenges & Problems With Transitioning To Renewable Energy

The Challenges With China’s Transition From Coal, To Natural Gas & Renewable Energy

25 Reasons Why We Don’t Use More Renewable Energy Worldwide (Barriers/Obstacles, & Challenges In Switching Over To Renewables)


So, for example, a country like China may not use as much renewable energy right now for consumption (even though they lead in installed capacity), because their current energy system is heavily reliant on coal.

But, there can also be general barriers common to many cities and countries.


Also, we’ve put together a guide comparing renewable energy sources:

Renewable Energy vs Fossil Fuels vs Nuclear: Comparison Guide


There’s several areas where renewable energy doesn’t compare as favorable as fossil fuels, such as in some capital cost, and variability/intermittency aspects.
