Ranked: Latin American Countries By Green Energy Use

The global push for increasing green energy use is well underway, as countries around the world are feeling pressure to revamp their climate-impacting practices.

But with different populations, energy use requirements, and access to natural resources, certain regions will have a more significant role to play. With a population of 664 million and an abundance of natural resources, Latin America (LatAm) is one such region.

How green is LatAm’s energy today? This graphic from Latinometrics charts countries’ electricity production from renewables relative to fossil fuels and highlights the significant disparities between certain nations.

Green Energy Use in Latin America

As of 2020, many LatAm countries actually produced 50% or more of their electricity from renewable sources including nuclear energy. Let’s take a deeper look at some of the outliers:

Paraguay

Hydropower is Paraguay’s primary renewable energy source, and plentiful. In fact, the country produces surplus electricity and exports the remainder to Argentina and Brazil. Altogether, 60% of Paraguay’s hydroelectric power is exported, contributing to 6% of its GDP.

The primary resource for this hydropower—the Itaipú Dam—sits between Paraguay and Brazil and is jointly owned by both. The dam is responsible for 79% of Paraguay’s total power capacity.

Costa Rica

Costa Rica has been running on at least 98% renewable energy since 2014. Both within the Americas and on a global scale, the country’s green energy usage ranks extremely high, primarily driven by hydropower:

Uranium: Powering the Cleanest Source of Energy

Uranium: Powering the Cleanest Source of Energy

The world’s energy needs are growing with its population. However, achieving a net-zero carbon economy while meeting our growing energy needs requires a larger role for clean, sustainable, and reliable sources. Nuclear is one such energy source.

The above graphic from the Sprott Physical Uranium Trust highlights how uranium is powering one of the cleanest and most reliable sources of energy in nuclear power.

The Cleanest Energy Sources

Although all energy sources have tradeoffs, some are better for the environment than others.

To find the cleanest sources of energy, Our World in Data calculated CO2-equivalent emissions per gigawatt-hour (GWh) of electricity generated over the lifecycle of power plants for different energy sources. This includes the footprint of raw materials, transport, and construction of power plants.

Energy SourceCO2-equivalent Emissions Per GWh (tonnes)Type
Coal820Fossil fuel
Oil720Fossil fuel
Natural Gas490Fossil fuel
Biomass78-230*Non-renewable
Hydro34Renewable
Solar5Renewable

Nuclear3Non-renewable

*Emissions from biomass vary depending on the type of fuel combusted.

It’s not surprising that coal, oil, and natural gas plants emit much more greenhouse gases than their renewable and non-renewable counterparts. In fact, emissions per GWh from coal power plants are roughly 273 times higher than nuclear power plants.

Hydropower offers a cleaner and renewable alternative to fossil fuels, however, the concrete and materials used in (Read more...)
