The limits of renewable energy and the case for degrowth

The energy transition is the focus of much discussion. To read the accounts in the mainstream media, one gets the impression that renewable energy is being rolled out quickly and is on its way to replacing fossil fuels without much ado while generating new green jobs. If the claims of Jeremy Rifkin are to be believed, renewable energy will become cheaper and cheaper, on the model of computers and telecommunications. But what is the current combined share of solar photovoltaic energy and solar thermal energy, wind and tidal energy, and geothermal energy? (I am not including hydroelectric power and biomass here. While they are arguably forms of renewable energy, they are typically looked at separately because, having reached maturity, they have limited potential for expansion, unlike solar and wind power which remain underexploited.) People tend to think it constitutes 5, 10 or even 20 percent of total energy production.

5 Challenges in Renewable Energy in 2021

Article | June 14, 2022

Energy is an important feature in the economic and political development of a country. In developed nations like the USA, energy expansion has now reached a point where renewable energy sources also play a large part in the production of electricity. To meet the energy demands of the country, most production of renewable energy comes from fossil fuels and other non-renewable energy sources. Around 25% of the world’s energy is generated with renewable energy resources- mainly solar, wind, hydropower, and in some cases, geothermal. It is one of the fastest-growing electricity sources. Renewable energy is collected from resources that are abundantly available in the environment, like the sun or wind. There has been a growing interest in renewable energy production as fossil fuels are depleting. In most parts of the world, renewable energy has become a primary source of energy production. Renewable energy is preferred as they produce fewer greenhouse gases than non-RE sources. There are several other advantages to renewable sources like lower carbon emissions, reduced air pollution, and other socioeconomic benefits. However, unlike non-RE sources, there are challenges in renewable energy like economic, political and regulatory barriers, structural, social, and technical challenges which require advancement in technology, and a heavy investment with a proper understanding of obstacles it faces. Some obstacles are due to technology associated with renewable energy, whereas others are because of policies, marketplace, regulations, and infrastructure. Impact of Covid-19 The Covid-19 pandemic has brought the world to a grinding halt. It has severely impacted individuals and businesses alike, with many of the latter being closed down permanently. Similarly, the pandemic has also impacted the expansion of clean energy systems by forcefully curbing any investments. The technology and adoption of renewables have been making uneven but sure progress. The global pandemic has slowed down this development. According to International Energy Agency, the global share of electricity supply from renewables had reached 28% in 2020 from 26% in 2019, but the growth is expected to slow down further. The total energy supply is set to reduce by 13% from 2019. This substantial decline can be attributed to supply chain disruptions, lockdown, and emerging financial problems. Transport biofuel production and renewable heat consumption are projected to decline due to lower industrial activity. Governments have an opportunity to promote and accelerate the use of clean energy by incentivizing building, technology, and infrastructure across the country. This would be crucial to rebuilding the economy, create jobs, and build efficiency. Capital Costs and Investment The most obvious challenge of widespread adoption of renewables is cost, predominantly infrastructure costs like building and installing solar and wind power plants. Although it is quite cheap to operate and maintain solar and wind power plants, installation becomes more and more expensive. Over the last few years, even though the prices of installation of solar panels has fallen significantly, it remains higher than non-renewables. On average, a 2-kilowatt solar panel system costs $4,159 after tax credits, whereas the capital cost of a gas-fired power plant would cost lesser than that. In the last two years, investment in renewables has increased, but that is only because the investments in fossil fuels have been rapidly falling. Clean energy investments still fall short of what is necessary to convert into a more sustainable future. To ensure continuous investment in sustainable energy, policymakers have to focus on short investment turnaround, focus on rapid environmental gains favoring cleaner energy generation. Power on demand One of the most significant challenges of renewables is the ability to provide power on demand. In the case of solar power, you only get energy during the day and only when it is sunny. As for wind energy, power is generated only when it is windy. There is an intermittent generation of power in renewables which wouldn’t be a problem if there were appropriate energy storage solutions. The biggest test in providing power on demand is storage. Even if homes, businesses, or states install wind energy systems or solar panels, storing the generated energy is still an unsolved issue. Opponents of renewable energy highlight the reliability factor on solar and wind to augment support for coal, gas, and nuclear plants, which provide baseload power. This argument is used by lobbyists to drive out investment into renewables, thus becoming a barrier to widespread adoption of wind and solar energy. Location challenges Renewable energy plants have grids that require a large area of land. It can be unappealing to customers to switch to renewable energy sources as it is conditional depending on the size of the land. Not all states and regions are apt to build solar panels or have wind turbines as they are dependent on the geographical location. For example, building solar panels in California makes more sense than building them in New York as the former has an abundant supply of both sun and land. Renewables operates on what is known as a decentralized model. In a decentralized power plant, small generating stations are spread across a larger area that works collectively to deliver power. In the case of coal, nuclear power, or natural gas, they are highly centralized and depend on fewer high output power plants. Siting Decentralized systems prove to be a problem for siting and transmission of energy created by solar or wind. Siting is needed to move blades or solar panels to large pieces of land. To do so requires to draw up contracts, negotiate, acquire permits, or build community relations; all of this can delay or kill a renewable project even before it begins. Businesses can incur additional charges due to demand and delivery which seems like a significant challenge for them. Utility services apply these charges to recover costs of purchasing energy and maintaining power lines and energy lost in the transmission system. Moving power sources closer to your business will help you avoid such preventable expenses. Transmission The next challenge to overcome in renewables is the transmission of generated electricity. Transmission means the transfer of electricity from where it is generated to where it is consumed. Most transmitters that exist in this day and age are built for coal and other fossil fuels and not renewables. To make things easier for transmission of clean energy, there needs to be a significant infrastructure and technological development, which cost a lot of money. Making the economics work with financing and siting can prove costly for developers and customers alike. Policies and Regulations Unfortunately, the fossil fuel industry is backed by multi-billionaires who wield a considerable amount of political influence. This severely affects the chances of expansion for the renewable industry. Industry experts estimate that the USA spends upwards of $60 billion on subsidies for fossil fuels every year. The taxpayers have helped fund the industry’s research and development, drilling, mining, and generation of electricity. Renewables like wind and solar enjoy much lesser subsidies and political backing. The fossil fuel industry has used its enormous power to spread misinformation about climate change. To increase public interest and investment in renewables, there need to be clear and concise legal procedures and regulatory policies. Having proper regulations in place creates a stable environment for investment and overcome hurdles and can anticipate the revenue streams. Large-scale renewable energy projects require a large amount of capital which is hindered by the failure of proper policies that fail to attract private players. Frequently Asked Questions What is a major challenge with using more renewable energy? Renewable energy is competing with fossil fuels and nuclear technology. Other major challenges include underdeveloped infrastructure and lack of economies of scale. What are the benefits of using renewable energy? Some benefits of using renewable energy are lower energy costs, reduction of emissions, massive positive impact on environment, and marketing opportunities for businesses. Is renewable energy cheaper than fossil fuels? Fossil fuels are subsidized which makes it cheaper at the beginning. However, renewables get cheaper to maintain over the years hence making it cheaper than fossil fuels. What is the cheapest source of renewable energy? Solar PV and on site wind are the cheapest sources of renewable energy sources. { "@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{ "@type": "Question", "name": "What is a major challenge with using more renewable energy?", "acceptedAnswer": { "@type": "Answer", "text": "Renewable energy is competing with fossil fuels and nuclear technology.

How viable is Underground Hydrogen Storage?

Article | July 29, 2022

Cleaner energy resources are the dire need of the hour and this is a known fact. While scientists and experts across the planet are striving hard to reduce our reliance on fossil fuels, our energy needs have never faced a downfall- thanks to rapid industrialization and urbanization. Although renewable resources like solar, wind, and hydro-electric power are the most popular alternatives, these are seasonal energy sources and the energy production from the same will not be similar all around the year. The fluctuations in production hence cannot always meet the energy demand of the population, and this makes the renewable energy sources not completely reliable. Solar Production v/s Demand of the same in a year What and How H2 is produced? Now, this is where Hydrogen- the first element of the periodic table comes to the spotlight with a solution. Being a gas, hydrogen fuel can very well cater to our energy needs and is produced from techniques including Thermochemical, Solar-Water splitting, electrolytic and biological processes. While the production of this cleaner energy source leaves a carbon footprint of about 830 million tonnes in the form of CO2 annually, the result being a zero-emission fuel is what makes H2’s future bright. Storage of H2 – the million-dollar question: Having almost cleared the need and methods of producing hydrogen fuel, we will be looking at an area that is usually not given much thought about and that is the storage of H2. As already mentioned, for time being let us consider hydrogen as an alternative to renewable resources which is utilized when the energy demand increases drastically. While producing the fuel in the nick of time is obviously undoable, sufficient storage of H2 anticipating the demand is the best choice. Like Natural Gas, Hydrogen is also compressed before storing to achieve lower volume and also because liquid hydrogen demands a 64% higher amount of energy for storage than its compressed gaseous counterpart. Storage tanks v/s Geological landforms: Compressed Hydrogen can be stored in surface storage vessels (like steel composite concrete vessels and in wind turbine towers) or in geological landforms like (salt caverns, depleted O&G reservoirs, and aquifers). Nevertheless, unlike the underground geological landforms which offer huge storage capacity owing to their sheer scale, the storage tanks which can range in size from a small bottle to a huge tank require high amounts of pressure to store an appreciable amount of H2 in it. Since these storage tanks are usually constructed on the surface, the pressure conditions in these tanks need to be artificially stimulated and thereby mount huge upfront costs when compared to their geological storage counterpart. H2 storage prices in Geological Landforms v/s Storage Vessels (in $/kg) The above is a table comparing the prices of Hydrogen storage in Geological landforms and Storage Vessels at different pressure conditions. It is visible from the table that it's about 218 times cheaper to store the same amount of hydrogen in Geological landforms than in storage vessels. Is geological storage truly a better option? Like any other storage option geological storage too has its pros and cons. From the erosion of pipelines to the tedious task of injecting the gas and maintaining it at apt pressure conditions, geological storage has its limitations. However, the important prerequisite is the availability of the suitable landform itself. While most of the Depleted O&G Reservoirs have already met all the requirements for a suitable Underground Hydrogen Storage (UHS) system, the presence of unrecoverable remnant fluids in it makes it both a boon and a bane. This is because the presence of remnant fluids like oil and gas satisfies the cushion gas need for efficient storage of H2 in the reservoir, chances of contamination of H2 by the same is also high. This is the reason why Aquifers too aren’t favorable underground landforms when it comes to hydrogen storage. Salt Caverns- the best UHS System? The problem of Hydrogen contamination in Depleted Oil & Gas reservoirs and aquifers leaves us to the next big suitable subsurface landform- salt caverns. Unlike the other two landforms, the problem of contamination can be prevented in these dome-like structures formed due to the upliftment of salt deposits and it is also found that about 98% of its storage efficiency can be used to store Hydrogen here. The reason behind its relatively expensive nature when compared to its other two counterparts is due to the process of salt removing or leaching that must be done before storing to ensure that the contamination of the gas is unheard of at least here. Suitable Conditions of UHS: As per Stefan Iglauer, the maximum amount of H2 can be stored at a depth of 1100m beneath the Earth’s surface and the capacity gradually decreases up until 3700 m depth beyond which the wettability of the gas increases as it percolates through the rocks and hence cannot be permanently immobilized. Conclusively it is found that suitable landforms formed at 1km depth can store up to 2.0 Mt of H2. Comparing this 2 MT storage capacity of Salt Caverns with the currently available storage tanks which can store about 800 kg of H2 in it, it is visible that geological landforms have a clear upper hand at least when it comes to storage capacity. Future of UHS: With demands for Hydrogen fuel estimated to grow at 5.48 % annually and the need for a suitable storage system of the same at 5.8% annually, the field of Underground Hydrogen Storage systems indeed has a bright scope. Moreover, to meet the large-scale needs of Industries, there is an imminent need to level up the storage capacity of H2 and by exploring suitable geological landforms across the globe, the estimated industrial need of 1200 kT/ year in 2050 can be met.

Technologies Shaping the Future of Renewable Energy

Article | June 8, 2022

Introduction Renewable energy has transformed our planet. It's raised awareness of global warming and climate change. Both governments and ordinary people are seeking to move from fossil fuels to renewable energy because of this awareness. Technology's involvement in this revolution cannot be understated. Thought a few years ago that solar energy would power average houses in small communities. Thanks to the widespread manufacture of lithium-ion batteries, EVs will be the next big thing. Major Renewable Energy Technologies Transforming the Future Power-to-X Despite the name, this is not a conspiracy theory about global dominance. Modern technology converts electricity into synthetic fuels, thermal energy, and hydrogen. This breakthrough technology can minimize fossil fuel dependence by focusing on synthetic ones. It can also help with efficient storage solutions. Green Appliances and Machines Leading household appliance makers are launching solar-powered appliances. This is a wonderful start toward minimizing family power expenses. Many households have begun to invest in gadgets such as solar air conditioners. Distributed Generation Systems Several locations are experimenting with distributed generation. This reduces dependence on a centralized grid and simplifies transmission and distribution. It also reduces grid dependability and failures. Electrification Most European nations are actively electrifying to cut carbon emissions. This is not the same as a power supply. Rather, it implies developing assets and infrastructure that can shift and aid in the adoption of electricity. Providing public EV charging stations is a step towards electrification. Closing Lines Prominent private companies such as Google, Apple, and Microsoft have made significant commitments to renewable energy in recent years. While some governments are actively attempting to make the shift, others have yet to take environmental challenges such as global warming and climate change seriously. Technological breakthroughs are helping to make the transition to renewable energy greener, quicker, and more economical.

Indigenous lands can be ground zero for a wind energy boom

Article | May 19, 2021

It all started about four years ago, when SUVs and pickup trucks drove uninvited onto their lands, remembers Olimpia Palmar, a member of the Indigenous Wayúu peoples, who historically have occupied the La Guajira desert in northern Colombia and Venezuela. "We started seeing these arijunas [Wayuúunaiki for non-native peoples] wearing construction helmets and boots and vests, getting out of the cars, checking the desert, and then leaving," she recalls. Word soon began circulating across the Guajira Peninsula, from the rancherías — the community’s rural settlements — to the few urban centers: The arijunas were offering money to those who would let them plant tall, slim towers on their lands to measure the wind. On La Guajira’s dusty earth, where few things grow, towers began to sprout. By 2019, at least 30 wind-measuring towers had risen on Wayúu land, according to a report by Indepaz, a nonprofit research center.

"Motivating consumers to make smarter energy decisions is paramount to achieving utility decarbonization goals,” said Chris Black, CEO of GridX. “Through our partnership with Bidgely, we are further reducing the mystery of how a consumer's energy choices correspond to their energy bills or grid impact. This results in a win for everyone. Customers get lower bills, utilities get more life out of their existing infrastructure, and customers and utilities are in sync in achieving their decarbonization goals.” Bidgely’s UtilityAI™ Platform, which provides hour-by-hour energy insights into customers’ usage patterns at the appliance level, combined with GridX’s industry-leading rate engine enables utilities to execute demand-side management strategies critical for supporting decarbonization and electrification goals. This integration enables utilities to: Improve rate analytics for tailoring new and existing plans to customer needs and utility objectives. Give customers rate comparisons that project the detailed impact to their bill across different rate options. Personalize cost simulations that inform customers on how potential changes impact future bills, for example: EV purchases, HVAC upgrades, solar PV and Time-of-Use enrollment. Deliver accurate appliance-level cost breakdowns across the bill cycle and hourly levels. Unlocking behind-the-meter cost savings opportunities also bolsters satisfaction and trust among utility customers. Through highly precise bill projections, rate comparisons and energy efficiency recommendations, consumers can understand how their individual usage affects bill statements and better control their energy costs. “Restructuring rate plans for better load shifting has become an imperative utility initiative, especially as electric vehicles, appliance electrification and weather-related grid strains become more prolific. By partnering with GridX, we are teaching consumers that when they use energy is as important as how much energy is used, and we are giving every kilowatt-hour consumed a dollar value to help drive simple and actionable behavioral changes,” said Abhay Gupta, CEO of Bidgely.
