In order to meet this mark, industries need to find sustainable sources of fuel in the near future, or be met with costly penalties. Up to now, the price of non-renewable fuel was too attractive for clean energy to be competitive. However, tighter regulations, major leaps in technology and state-level commitment have birthed a new era of renewable energy.

Energy you can bank on

According to Bloomberg analysts, USD 10.2 trillion will be spent on new power generation by 2040, 72 percent of which will go towards wind and solar photovoltaic plants. By then, the cost of solar electricity will drop 66 percent, meaning by 2021, solar power will be cheaper than energy from coal in China, India, Mexico and the UK. The cost of onshore wind power will decrease by 47 percent by 2040, and offshore wind power by 71 percent thanks to more advanced and cost-effective wind turbines.  

Renewable energy is getting more and more competitive, and companies who don’t make the switch to clean fuel will be left out of the race.

However, electricity doesn’t fall from trees.

It falls from steel! Tons of steel (literally) are used to extract and convert energy from renewable energy sources.

Wind Energy

Most wind turbines are made of steel, and for an average wind turbine, 140 tons of steel are used. That accounts for 80 percent of all the materials that go into the tower, the nacelle, rotor blades and its supporting facilities. The majority of steel is used to make the tower which serves as the foundation on which the blades turn to generate energy. There are several types of turbine towers, such as steel-concrete hybrid towers, steel truss towers and steel lattice towers, but about 90 percent of all wind turbine towers are made of tubular steel. Also, steel’s non-corrosive properties maximize the lifetime of wind turbines and minimize maintenance costs.

Solar Energy

Solar electricity is one of the most promising types of renewable energy. By as soon as 2030, it can make up 13 percent of the world’s energy, and by 2050, the sun will be the largest source of electricity on earth. And steel will be soaking it all up – the sunlight that is. Steel makes up not only the frame of the solar panels, but the heat exchangers and other related infrastructure. Stainless steel is a great choice for solar panel frames because it is dense, high in strength and has the greatest corrosion-resistance than other light metals.

Geothermal Energy

Mother earth just keeps on giving. There are about 1400 TWh of geothermal energy in the earth’s core that can be harvested by 2050. Geothermal energy gives off extreme heat, so it is vital for the heat exchangers, condensers, pipes, filters, pumps and valves to be corrosion resistant. Otherwise, maintenance costs would be unsustainable and corrosion can contaminate the water as well. That’s why most of the infrastructure related to geothermal energy is made of iron castings, stainless steel and steel alloys.

Tidal Energy

There’s plenty of energy in the sea as well. In the world’s oceans, there are about 1 million megawatts of usable tidal energy. Steel makes up most parts of the underwater turbines including the nacelles, support structures and underlying piles for a sturdy and sustainable power source. As with other renewable energy, increasing the lifetime and decreasing maintenance costs will determine the competitiveness of tidal energy. Thus, stainless steel is the go-to material for corrosion resistance. The infrastructure related to tidal energy extraction is massive in scale and will call for thousands and thousands of pounds of steel to construct.  

Korea is the largest source of tidal energy in the world, with 552.7 GHw of electricity harvested from Siwha Lake every year. It’s also where steelmaker POSCO is located to provide the necessary types and grades of steel for renewable energy production.

POSCO E&C has its own solar, wind, tidal and refuse-derived fuel (RDF) plants, which makes sure even industrial wastes get turned into energy. The company was also the first company in Korea to build a solar power plant in 8 different regions capable of generating 31.2MW of solar electricity.

In order to stay competitive in the market, industries are already using or transitioning towards renewable energy sources to fuel their business activities. As governments around the globe also commit to a greener future, the demand for steel used in renewable energy infrastructure will see a significant boost.

The Demographic Cliff

Economic forecaster and author of “The Demographic Cliff,” Harry Dent, says people between the ages of 45 and 49 are typically the heads of families and spend the most money on things like housing, cars and appliances. As populations age, fewer people will make up the prime spending age group of 45 to 49, and there will be a drop in consumption. Dent calls this the “demographic cliff,” or the “consumption cliff”. The world has seen proof of this theory in places like Japan, Western Europe and the U.S., where economic downturn has come at times of a population downturn.

Japan, for example, was one of the first nations to experience a demographic cliff in the early 90s. It was also the time when its stocks and real estate prices fell 60 percent. Those prices never rebounded. Since then, the country has spiraled into debt (the world’s highest at 246 percent of GDP) with an increasingly aging workforce and stagnant economy. From 2010 to 2015, Japan’s population decreased by almost 1 million people, and the government is working to prevent the population from falling below 100 million by 2060.

Dent also argued that the American baby boomers of the early 60s peaked in 2007, at their highest spending age, and then the economy experienced a downturn, in the form of the 2008 financial crisis. Since then, the U.S. government has added USD 8.4 trillion in debt. Although the reasons for the 2008 crisis are complex, Dent does prove a point: demographics have a huge impact on economics.

Falling Steel Consumption

As it was with Japan and the U.S., consumption will decrease in industries critical to the steel market. In Japan, steel consumption decreased 81 percent from 1995. According to a report by POSCO Research Institute, construction accounts for 42 percent of total steel demand and the auto industry accounts for 18.5 percent. Decreased spending on homes and cars due to the demographic cliff will have a significant impact on the steel industry. Decreased demand in other industries such as machinery and home appliances will also affect steel demand.

Moreover, manufacturers will be faced with the problem of a shrinking workforce. Those entering the workforce will do so with the burden of sustaining government programs with a larger portion of their paychecks, and employers will start to notice the gaps not only in age but experience and skill as well. With fewer people entering the workforce, employers will be forced to outsource jobs and governments may factor in more lenient immigration policies to fill the gaps.

How can Steelmakers Prepare for the Future?

Although there is no quick solution to the aging population and low birthrates, steelmakers can start preparing for a demographic cliff in two ways. Enter markets with growing populations and introduce smart technology to fill the human labor gap.

In developing countries in Asia and Africa, there are little signs of population and economic stagnation. As those countries invest in their infrastructure and start to consume more homes, cars and appliances, steel will be in high demand, more than those countries can produce domestically.

India is one of the countries with a growing population. The government is undergoing numerous projects to boost its economy and prepare for growth, including the project to boost its solar energy market. The Indian government has plans to invest USD 100 billion and 100 gigawatts (GW) of solar capacity for the country by 2022. Steel is a vital part of solar panels and suppliers like POSCO are already partnering with Indian firms to provide the leading material and technology for India to meet its growing renewable energy demand. POSCO also has partnerships in the U.S., Bangladesh, Myanmar, Uzbekistan and more to help each country fill their supply gaps.

In order to fill the domestic labor shortage, POSCO is incorporating leading AI technology, IoT and big data to its smart factories.

It is true that today’s developed nations have reached, or are heading towards a demographic cliff. Japan is a classic example of how detrimental a shrinking and aging population can be for a country’s economy. Governments and industries have to start factoring in demographics to their long-term strategies and plan for a changing future.

India’s Solar Energy Market

Solar energy is an extremely vital and rapidly developing industry in India. From May 2014 to March 2017, the country quadrupled its solar generation capacity. The average cost of solar electricity is 18 percent below the average price of coal-fired energy, making solar electricity the cheapest form of alternative fuel in India.  

The Indian government is fully supportive of this market, setting a goal of USD 100 billion in investment and 100 gigawatts (GW) of solar capacity for the country by 2022. Solar is particularly important in the rural areas of India where there is limited access to electricity, so the government plans to install solar lanterns, home and street lighting systems and solar cookers.

In November 2017, India became home to the world’s largest solar farm in Kamuthi, Tamil Nadu. The farm covers 2,500 acres with 2.5 million solar modules. India’s solar electricity market has the potential for further expansion, and global suppliers and manufacturers are taking notice.  

POSCO India, a Partner for PV Structure Manufacturers

POSCO is a steel supplier making headway into the Indian solar energy market with its innovative and sustainable products. In September, POSCO India took part in the 2017 Renewable Energy India Expo in Greater Noida.

POSCO’s Booth at the 2017 Renewable Energy India showcased PV structures made of PosMAC steel.

POSCO India Chairman and Managing Director Gee Woong Sung and other POSCO employees showcased POSCO’s solar (PV) structures, constructed from PosMAC steel (POSCO Magnesium Alloy Coating Product). “By the end of this year, we will complete the Indian solution marketing system, which will supply not only steel but also solar PV structures,” said Sung. “In 2018, we will further expand PosMAC sales in India.”

By the end of the event, POSCO signed memorandums of understanding with four major manufacturers of PV structures in India, and will be supplying 49,000 tons of PosMAC with a goal of increasing production to 60,000 tons by 2018.

Solar Electricity Solutions with PosMAC

PosMAC steel has great potential in India because it is ideal for solar panel application. It is ultra corrosion-resistant and cost-effective. Watch the video below to find about the technology behind PosMAC.

A typical PV unit lasts for about three decades, during which a failure of any part would lead to an early demise. PosMAC steel provides weather resistance and is also less expensive than other PV materials like stainless steel.

Despite its varying climate, India is a country with excellent conditions for capturing and using solar energy, with roughly 300 days of sunshine each year. Along with vibrant market conditions, heavy government backing as well as a large consumer base, India’s new and renewable energy industry is set for growth. As solar energy is the cheapest form of alternative fuel, solar PV unit manufacturers will have plenty of business opportunities in India’s growing market.
