Visualizing The Global Transition to Green Energy

A fully green future could be closer than you think. With each passing year, the steadily declining price of renewable energy makes it increasingly competitive against fossil fuels.

Today’s infographic from Raconteur breaks down the material shift towards renewable energy, and where in the world it’s taking place.

Time to go green

A recent United Nations report estimates that renewables must make up 70% to 85% of electricity by 2050 to combat the dire effects of climate change.

The good news? Embracing renewable energy is becoming easier on the wallet. Most renewable energy sources are becoming cheaper and quicker to produce, and it’s speeding up widespread adoption.

Cost of electricity per energy source ($ per KWh)20102017
Concentrating solar power$0.33$0.22
Offshore wind$0.17$0.14
Solar photovoltaic$0.36$0.10
Biomass$0.07$0.07
Geothermal$0.05$0.07
Onshore wind$0.08$0.06
Hydro$0.04$0.05

The price of solar photovoltaic cells are projected to dip dramatically over this seven-year period, as solar panel infrastructure moves away from being an experimental technology, and into a trusted energy source easily replicated at scale. Solar also received the most new investment by energy type in 2017, up 18% from the previous year.

Of course, it won’t happen overnight. Even as the world continues to electrify, coal will still make up almost one-third of the world’s energy mix in 2040, while renewables will only be at 25%.

Nevertheless, concentrated efforts to curb our reliance on coal are signals that the fossil fuel is on its way out, and new investment in green energy sources is on the rise in most regions.

The Renewables Race

It’s perhaps not surprising that China is leading the change in renewable growth. The nation tops the list of spenders, spending more on green energy than the United States and Europe combined.

New Investment by Region2016 ($ billion)2017 ($ billion)% Change
Total$274$279.82%
China$96.9$126.631%
Europe$64.1$40.9-36%
United States$43.1$40.5-6%
Other Asia and Oceania$35.7$31.4-12%
Other Americas$6$13.4124%
Middle East & Africa$9$10.111%
India$13.7$10.9-20%
Brazil$5.6$68%

In places where a consistent and reliable source of energy is hard to come by, people are looking to clean energy as a way to leapfrog ahead of using the carbon-intensive electricity grid entirely.

Take Ethiopia for example: the $4 billion Grand Ethiopian Renaissance Dam (GERD) project along the Nile River will help meet the area’s rising energy demands. Once completed, it will be the largest dam on the continent and generate around 6,450 MW of power.

This trifecta of innovation, investment, and falling costs could be the answer to bolstering renewable energy infrastructure for decades to come – and it will be interesting to see the ultimate pace at which green energy supply comes online, and what that means for the world.

Visualizing Copper’s Role in the Transition to Clean Energy

A clean energy transition is underway as wind, solar, and batteries take center stage. Here’s how copper plays the critical role in these technologies.

Published

A future powered by renewables is not in the distant horizon, but rather in its early hours.

This new dawn comes from a global awareness of the environmental impacts of the current energy mix, which relies heavily on fossil fuels and their associated greenhouse gas emissions.

Technologies such as wind, solar, and batteries offer renewable and clean alternatives and are leading the way for the transition to clean energy. However, as with every energy transition, there are not only new technologies, but also new material demands.

Copper: A Key Piece of the Puzzle

This energy transition will be mineral intensive and it will require metals such as nickel, lithium, and cobalt. However, one metal stands out as being particularly important, and that is copper.

Today’s infographic comes to us from the Copper Development Association and outlines the special role of copper in renewable power generation, energy storage, and electric vehicles.

Copper and the Clean Energy Transition

Why Copper?

The red metal has four key properties that make it ideal for the clean energy transition.

  1. Conductivity
  2. Ductility
  3. Efficiency
  4. Recyclability

It is these properties that make copper the critical material for wind and solar technology, energy storage, and electric vehicles.

It’s also why, according to ThinkCopper, the generation of electricity from solar and wind uses four to six times more copper than fossil fuel sources.

Copper in Wind

A three-megawatt wind turbine can contain up to 4.7 tons of copper with 53% of that demand coming from the cable and wiring, 24% from the turbine/power generation components, 4% from transformers, and 19% from turbine transformers.

The use of copper significantly increases when going offshore. That’s because onshore wind farms use approximately 7,766 lbs of copper per MW, while an offshore wind installation uses 21,068 lbs of copper per MW.

It is the cabling of the offshore wind farms to connect them to each other and to deliver the power that accounts for the bulk of the copper usage.

Copper in Solar

Solar power systems can contain approximately 5.5 tons of copper per MW. Copper is in the heat exchangers of solar thermal units as well as in the wiring and cabling that transmits the electricity in photovoltaic solar cells.

Navigant Research projects that 262 GW of new solar installations between 2018 and 2027 in North America will require 1.9 billion lbs of copper.

Copper in Energy Storage

There are many ways to store energy, but every method uses copper. For example, a lithium ion battery contains 440 lbs of copper per MW and a flow battery 540 lbs of copper per MW.

Copper wiring and cabling connects renewable power generation with energy storage, while the copper in the switches of transformers help to deliver power at the right voltage.

Across the United States, a total of 5,752 MW of energy capacity has been announced and commissioned.

Copper in Electric Vehicles

Copper is at the heart of the electric vehicle (EV). This is because EVs rely on copper for the motor coil that drives the engine.

The more electric the car, the more copper it needs; a car powered by an internal combustion engine contains roughly 48 lbs, a hybrid needs 88 lbs, and a battery electric vehicle uses 184 lbs.

Additionally, the cabling for charging stations of electric vehicles will be another source of copper demand.

The Copper Future

Advances in technologies create new material demands.

Therefore, it shouldn’t be surprising that the transition to renewables is going to create demand for many minerals – and copper is going to be a critical mineral for the new era of energy.

How Much Oil is in an Electric Vehicle?

It is counterintuitive, but electric vehicles are not possible without oil – these petrochemicals bring down the weight of cars to make EVs possible.

How Much Oil is in an Electric Vehicle?

When most people think about oil and natural gas, the first thing that comes to mind is the gas in the tank of their car. But there is actually much more to oil’s role, than meets the eye…

Oil, along with natural gas, has hundreds of different uses in a modern vehicle through petrochemicals.

Today’s infographic comes to us from American Fuel & Petrochemicals Manufacturers, and covers why oil is a critical material in making the EV revolution possible.

Pliable Properties

It turns out the many everyday materials we rely on from synthetic rubber to plastics to lubricants all come from petrochemicals.

The use of various polymers and plastics has several advantages for manufacturers and consumers:

  1. Lightweight
  2. Inexpensive
  3. Plentiful
  4. Easy to Shape
  5. Durable
  6. Flame Retardant

Today, plastics can make up to 50% of a vehicle’s volume but only 10% of its weight. These plastics can be as strong as steel, but light enough to save on fuel and still maintain structural integrity.

This was not always the case, as oil’s use has evolved and grown over time.

Not Your Granddaddy’s Caddy

Plastics were not always a critical material in auto manufacturing industry, but over time plastics such as polypropylene and polyurethane became indispensable in the production of cars.

Rolls Royce was one of the first car manufacturers to boast about the use of plastics in its car interior. Over time, plastics have evolved into a critical material for reducing the overall weight of vehicles, allowing for more power and conveniences.

Timeline:

  • 1916
    Rolls Royce uses phenol formaldehyde resin in its car interiors
  • 1941
    Henry Ford experiments with an “all-plastic” car
  • 1960
    About 20 lbs. of plastics is used in the average car
  • 1970
    Manufacturers begin using plastic for interior decorations
  • 1980
    Headlights, bumpers, fenders and tailgates become plastic
  • 2000
    Engineered polymers first appear in semi-structural parts of the vehicle
  • Present
    The average car uses over 1000 plastic parts

Electric Dreams: Petrochemicals for EV Innovation

Plastics and other materials made using petrochemicals make vehicles more efficient by reducing a vehicle’s weight, and this comes at a very reasonable cost.

For every 10% in weight reduction, the fuel economy of a car improves roughly 5% to 7%. EV’s need to achieve weight reductions because the battery packs that power them can weigh over 1000 lbs, requiring more power.

Today, plastics and polymers are used for hundreds of individual parts in an electric vehicle.

Oil and the EV Future

Oil is most known as a source of fuel, but petrochemicals also have many other useful physical properties.

In fact, petrochemicals will play a critical role in the mass adoption of electric vehicles by reducing their weight and improving their ranges and efficiency. In According to IHS Chemical, the average car will use 775 lbs of plastic by 2020.

Although it seems counterintuitive, petrochemicals derived from oil and natural gas make the major advancements by today’s EVs possible – and the continued use of petrochemicals will mean that both EVS and traditional vehicles will become even lighter, faster, and more efficient.
