What powers the World Coal vs Renewables

Electricity generated by new wind and solar helped to force a record fall in global coal power in 2020.

Electricity from Renewables vs. Coal in G20 Nations

As the COVID-19 pandemic has forced people to work and shop from home, cancel gatherings, and reduce the use of transportation, it has also paused the world’s rising demand for electricity.

The pandemic has opened a window of opportunity to reduce the share of power generated by fossil fuels. When demand for electricity drops, coal plants are usually switched off first since the process of burning fuels constantly runs up costs. In contrast, renewables such as wind and solar plants, once built, have significantly lower running costs.

This infographic based on Ember’s Global Electricity Review shows how wind and solar generation rose robustly in 2020 by 15% (+314 TWh), compared to 2019. That helped coal use to fall a record 4% (-346 TWh).

Accelerating the Use of Renewables

Wind and solar produced 9.4% of the world’s electricity last year, doubling from 4.6% in 2015.

As you can see in the table above, many G20 countries now get around a tenth of their electricity from wind and solar, including India (9%), China (9.5%), Japan (10%), Brazil (11%), the U.S. (12%), and Turkey (12%).

Europe led wind and solar generation around the world, with Germany producing 33% and the United Kingdom at 29%. Overall, electricity demand fell 3.5% in the European Union.

Is This the End of Coal?

Coal generation collapsed almost everywhere in 2020 compared to 2019, with large falls in the U.S. (-20%), EU (-20%), and India (-5%).

China was the only G20 nation to show a large increase in coal generation (+1.7%). Overall, the country saw a 4% increase in electricity demand in 2020, as it was the first to restart production after the first months of the COVID-19 crisis.

China is now responsible for 53% of the world’s coal-fired electricity, up from 44% in 2015.

Clean Energy Jobs creation by State

The Growth of Clean Energy Jobs by State

As the world is slowly moving towards a carbon-free future, job prospects within the renewable energy industry will see a boom in the coming years. Ranging from environmental scientists to renewable energy generation technicians and engineers, clean energy jobs are growing.

Between the shuttering of coal plants and companies making efforts to use renewable sources of energy, the United States on its own could see the creation of 5 million net new jobs within the energy-supply sector, driven by clean energy.

These jobs offer a more sustainable and high-paying alternative for the current and new workforce, especially in some of the country’s highly fossil-fuel-dependent states.

Based on analysis presented by Princeton University, the above infographic visualizes the forecasted change in energy-supply jobs in every state from 2019 to 2030 and up until 2050, in a net-zero scenario.

Shift in Energy Supply Jobs by 2030: Texas on the Forefront

Between 2020 and 2021, jobs in the oil and gas sector saw a 9% decline in Texas, a reduction of more than 55,000 in the state. Despite this, Texas is still one of the largest oil and natural gas producers, employing the highest number of people.

A rapid rise in employment in the clean energy industry will compensate for this decline in fossil fuel sector jobs. Texas fossil fuel unions have also signed onto the climate action plan and vowed to create more jobs in the clean energy sector.

In the process, Texas will see nearly 135,000 net new energy-supply jobs by 2030, more than any other state.

Here’s a look at the number of forecasted net new energy-supply jobs in the rest of the country:

Shift in Energy Supply Jobs by 2050: Wisconsin Advances

Wisconsin has stated its desire to transition to 100% clean energy by 2050, growing the state’s economy by more than $21 billion.

According to Princeton, Wisconsin could also introduce more than 46,000 net new energy-supply jobs by 2050, a tremendous leap over the state’s 863 new jobs forecasted through 2030.

Note: Negative values indicate a decline in energy-supply jobs by 2050.

The state of Wyoming has the second-highest change in energy supply jobs, going from 2,400 jobs by 2030 to nearly 62,000 by 2050. Meanwhile, California, Florida, and Texas will continue their commitment to being leaders and introducing more clean energy-supply jobs by 2050.

The only states that will see a decline in clean energy jobs between their 2030 and 2050 totals are the northeastern states of Connecticut, New Jersey, and Massachusetts.

Most states have taken measures to create more sustainable and high-paying jobs without leaving the current workforce in the lurch. On average, U.S. states will see an increase of 105,000 energy-supply jobs by 2050.

As the states and the country make this transition and federal and private investment in the renewable energy industry increases, it’ll be interesting to keep track of how new clean energy jobs impact the economy.

What Are the Five Major Types of Renewable Energy?

Renewable energy is the foundation of the ongoing energy transition. What are the key types of renewable energy, and how do they work?

The Renewable Energy Age

Awareness around climate change is shaping the future of the global economy in several ways.

Governments are planning how to reduce emissions, investors are scrutinizing companies’ environmental performance, and consumers are becoming conscious of their carbon footprints. But no matter the stakeholder, energy generation and consumption from fossil fuels is one of the biggest contributors to emissions.

Therefore, renewable energy sources have never been more top-of-mind than they are today.

The Five Types of Renewable Energy

Renewable energy technologies harness the power of the sun, wind, and heat from the Earth’s core, and then transforms it into usable forms of energy like heat, electricity, and fuel.

The above infographic uses data from Lazard, Ember, and other sources to outline everything you need to know about the five key types of renewable energy:

Energy Source% of 2021 Global Electricity GenerationAvg. levelized cost of energy per MWh
Hydro 💧 15.3%$64
Wind 🌬 6.6%$38
Solar ☀️ 3.7%$36
Biomass 🌱 2.3%$114
Geothermal ♨️ <1%$75

Editor’s note: We have excluded nuclear from the mix here, because although it is often defined as a sustainable energy source, it is not technically renewable (i.e. there are finite amounts of uranium).

Though often out of the limelight, hydro is the largest renewable electricity source, followed by wind and then solar.

Together, the five main sources combined for roughly 28% of global electricity generation in 2021, with wind and solar collectively breaking the 10% share barrier for the first time.

The levelized cost of energy (LCOE) measures the lifetime costs of a new utility-scale plant divided by total electricity generation. The LCOE of solar and wind is almost one-fifth that of coal ($167/MWh), meaning that new solar and wind plants are now much cheaper to build and operate than new coal plants over a longer time horizon.

With this in mind, here’s a closer look at the five types of renewable energy and how they work.

1. Wind

Wind turbines use large rotor blades, mounted at tall heights on both land and sea, to capture the kinetic energy created by wind.

When wind flows across the blade, the air pressure on one side of the blade decreases, pulling it down with a force described as the lift. The difference in air pressure across the two sides causes the blades to rotate, spinning the rotor.

The rotor is connected to a turbine generator, which spins to convert the wind’s kinetic energy into electricity.

2. Solar (Photovoltaic)

Solar technologies capture light or electromagnetic radiation from the sun and convert it into electricity.

Photovoltaic (PV) solar cells contain a semiconductor wafer, positive on one side and negative on the other, forming an electric field. When light hits the cell, the semiconductor absorbs the sunlight and transfers the energy in the form of electrons. These electrons are captured by the electric field in the form of an electric current.

A solar system’s ability to generate electricity depends on the semiconductor material, along with environmental conditions like heat, dirt, and shade.

3. Geothermal

Geothermal energy originates straight from the Earth’s core—heat from the core boils underground reservoirs of water, known as geothermal resources.

Geothermal plants typically use wells to pump hot water from geothermal resources and convert it into steam for a turbine generator. The extracted water and steam can then be reinjected, making it a renewable energy source.

4. Hydropower

Similar to wind turbines, hydropower plants channel the kinetic energy from flowing water into electricity by using a turbine generator.

Hydro plants are typically situated near bodies of water and use diversion structures like dams to change the flow of water. Power generation depends on the volume and change in elevation or head of the flowing water.

Greater water volumes and higher heads produce more energy and electricity, and vice versa.

5. Biomass

Humans have likely used energy from biomass or bioenergy for heat ever since our ancestors learned how to build fires.

Biomass—organic material like wood, dry leaves, and agricultural waste—is typically burned but considered renewable because it can be regrown or replenished. Burning biomass in a boiler produces high-pressure steam, which rotates a turbine generator to produce electricity.

Biomass is also converted into liquid or gaseous fuels for transportation. However, emissions from biomass vary with the material combusted and are often higher than other clean sources.

When Will Renewable Energy Take Over?

Despite the recent growth of renewables, fossil fuels still dominate the global energy mix.

Most countries are in the early stages of the energy transition, and only a handful get significant portions of their electricity from clean sources. However, the ongoing decade might see even more growth than recent record-breaking years.

The IEA forecasts that, by 2026, global renewable electricity capacity is set to grow by 60% from 2020 levels to over 4,800 gigawatts—equal to the current power output of fossil fuels and nuclear combined. So, regardless of when renewables will take over, it’s clear that the global energy economy will continue changing.
