[Slideshow] Powering New York

Imagine that overnight all power infrastructure in New York were to disappear. Then, starting from scratch, we could build anything we wanted: a giant solar array that stretches to the horizon, the world’s biggest windfarm, or a mega nuclear facility.

What would it take to power the Big Apple for a year with each individual energy source?

We’ve crunched the numbers for oil, natural gas, liquefied natural gas, solar, wind, and hydro. Then, we visualized what is needed for each to be hypothetically feasible as the city’s only source of energy. (Note: we’ve included some notes on our calculations at the bottom of this page.)

The results are quite mind boggling. For example, to facilitate New York City’s average power needs, you would need 12.8 km² of solar panels, enough to cover a good chunk of New Jersey. The average distance one can see into the horizon is 5km, which means that one would be able to see solar panels as far as the eye can see.

Another interesting example: powering New York City with hydroelectric based on average power needs would mean 14 Hoover Dams, each which produce about 4.2 billion kWh per year in energy. Using wind power, about half of Long Island would need to be converted into the world’s biggest wind farm to power New York City. That’s exponentially bigger than the current biggest wind farm in the United States, which is in the Tehachapi-Mojave region in California and has a nameplate capacity of 1,320 MW.

Quick notes on calculations

This presentation is for visualization purposes, and isn’t fully realistic on a technical basis because in reality, the supply and demand of energy is not constant. The city’s power needs fluctuate during base and peak load times. In terms of supply, the wind is not always blowing and the sun isn’t always shining. We based our numbers off of average electricity consumption, assuming that energy can be banked in times of surplus and used during times of deficiency.

We used some assumptions for the efficiency as well. For example, that a power plant burning oil has an efficiency of 533 kWh per barrel, or that our wind farm uses 1.5 MW turbines that have a capacity factor of 25%.

Ranked: The World’s Largest Energy Sources

As global population grows, our energy demand grows as well. Here are the largest energy sources in the world and how much electricity they generate.

Published

The World’s Largest and Most Notable Energy Sources

Every day, humans consume roughly 63,300,000 megawatt-hours (MWh) of electricity to power our homes, workplaces, and vehicles─about the same produced by over 5,700 Hoover Dams.

While present-day electricity generation is slanted heavily in favor of coal and gas on a global basis, renewable sources have started to gain ground.

Today’s graphic from Information is Beautiful lists the world’s largest energy sources and their energy outputs. These power plants are ranked using the daily megawatt-hour (MWh), the amount of energy a power source generates in a day.

Relying on Renewables

Located in the United Kingdom, Drax Power Station is the world’s largest biomass plant, powered chiefly by burning wood. Originally a coal-fired plant, Drax is expected to fully phase out coal by the year 2025.

Meanwhile, Tengger Desert Solar Park in China was the biggest solar operation until 2018, but it has since been displaced by the Shakti Sthala plant in India. The latter uses only solar panels─no mirrors─to generate energy from the sun.

Overall, solar photovoltaics have experienced the highest growth of all energy source segments, showing 31% annual growth─nearly triple the rate of wind power according to the International Energy Association (IEA).

Untapped Potential?

Currently, 27% of the world’s power comes from renewable energy sources such as solar, wind, hydro, biomass, and other similar resources.

However, according to back-of-the-envelope calculations, the potential for renewables is far beyond existing generation capacity. In fact, humans are just using 0.81% of solar’s potential generation capacity, and 0.57% of the potential from wind.

% of Potential Used0.81%0.57%13.3%0.41%

Non-renewable Energy Sources

Nuclear power plants have perhaps the strongest stigma against them─largely due to international disasters such as Chernobyl and Fukushima.

However, nuclear power plants are still the most efficient energy sources, sitting at over 90% average capacity.

The largest nuclear plant (by MW) in the world, Kashiwazaki-Kariwa, is currently shut down due to damage from a 2007 earthquake, and awaiting confirmation to restart operations. As a result, the Bruce Nuclear Generating Station in Canada now holds the title of the largest operating reactor in the world. The plant currently generates about 30% of Ontario’s power.

In 2018, coal is still being used to generate roughly 38% of the world’s total electricity, followed by natural gas with a 23% share.

The Future of Energy Potential

Fittingly, the graphic also shows daily energy outputs for Google and Bitcoin usage. This data helps remind us that our online activity also consumes energy─something that will be top of mind as technology continues to advance and humans need to use more energy through our internet-enabled devices.

Understanding humanity’s need for energy is a daunting endeavor, but it’s critical to ensuring our planet has a sustainable source of energy for generations to come.

All the World’s Coal Power Plants in One Map

Today’s interactive map shows all of the world’s coal power plants, plotted by capacity and carbon emissions from 2000 until 2018.

All The World’s Coal Power Plants in One Map

The use of coal for fuel dates back thousands of years.

Demand for the energy source really started to soar during the Industrial Revolution, and it continues to power some of the world’s largest economies today. However, as the clean energy revolution heats up, will coal continue to be a viable option?

Today’s data visualization from Carbon Brief maps the changing number of global coal power plants operating between 2000 and 2018. The interactive timeline pulls from the Global Coal Plant Tracker’s latest data and features around 10,000 retired, operating, and planned coal units, totaling close to 3,000 gigawatts (GW) of capacity across 95 countries.

On the map, each circular icon’s size represents each plant’s coal capacity in megawatts (MW). The data also highlights the type of coal burned and the CO₂ emissions produced as a result.

A Precarious Power Source

Throughout its history, coal has been used for everything from domestic heating and steel manufacturing, to railways, gas works, and electricity. The fuel played a pivotal role in powering economic development, and had a promising future with a flurry of plant openings.

However, in 2016, coal output dropped by 231 million tons of oil equivalent (Mtoe). Combined with a rapid slowdown of new plants being built, total coal units operating around the world fell for the first time in 2018.

With the remaining fleet of plants operating fewer hours than ever, plant closures have been triggered in South Africa, India, and China—steadily eroding coal’s bottom line. Industry trends have also forced a wave of coal companies to recently declare bankruptcy, including giants such as Peabody Energy and Alpha Natural.

Can Coal Compete with Clean Energy?

Today, coal is experiencing fierce competition from low-priced natural gas and ever-cheaper renewable power—most notably from wind and solar. Further, solar power costs will continue to decline each year and be cut in half by 2020, relative to 2015 figures.

Natural gas surpassed coal as America’s #1 power source in 2016, with the total share of power generated from coal tumbling from 45% in 2010 to 28% in 2018. By next year, the role of coal is expected to be further reduced to 24% of the mix.

On the interactive visualization, the decline of coal is especially evident in 2018 as plant closures sweep across the map. The chart shows how several countries, notably China and India, have been closing many hundreds of smaller, older, and less efficient units, but replacing them with larger and more efficient models.

As of today, China retains the largest fleet of coal plants, consuming a staggering 45% of the world’s coal.

Towards a New Reality

Coal is the most carbon intensive fossil fuel, and for every tonne of coal burned there are approximately 2.5 tonnes of carbon emissions. The International Energy Agency states that all unabated coal must be phased out within a few decades if global warming is to be limited.

Despite these warnings, global coal demand is set to remain stable for the next five years, with declines in the U.S. and Europe offset by immediate growth in India and China. The latter are the main players in the global coal market, but will eventually see a gradual decline in demand as they move away from industrialization.

A total phaseout of unabated coal is planned by 14 of the world’s 78 coal-powered countries, with many of these countries working to convert coal capacity to natural gas.

As the price of premium solar generation drops steadily, and innovation in renewable energy technology becomes more prominent, the world is shifting its attention to a clean energy economy. A global revival of coal looks less and less likely—and the fossil fuel might very well one day become obsolete.
