Let’s Start With: What Are Renewable Energy Systems?


Renewable Energy Systems use energy from self-replenishing sources, including the sun, wind, water, etc., to generate electricity and power. Hence, energy created using RES is defined as "energy derived from resources that are regenerative or for all practical purposes cannot be depleted."

To do this, Renewable Energy Systems leverage solar energy capture, hydroelectric, geothermal, biomass and other naturally available resources. Their capacity to generate electricity without tapping into finite resources or emitting greenhouse gases makes them renewable and sustainable. Moreover, RES provides a sustainable alternative to fossil fuels, supporting the reduction of carbon emissions and other harmful byproducts of fossil fuels. Sounds like step one to creating Technoland!

Yet, RES is a relatively new technology. Here’s why and how it evolved over time.
 

Evolution And Origins Of Renewable Energy Systems


One of the main reasons behind the development of Renewable Energy Systems is the inevitable depletion of fossil fuel reserves. With alternatives such as RES, we could achieve a truly sustainable and pollution-free energy source to power our businesses, homes and industries. Here’s how it came about:
   

  • Pre-20th Century

    The earliest use of wind and water mills for mechanical power dates back to ancient civilizations, like the Greeks and Romans. Energy consumption was a fraction back then and there was no real thought of energy creation to power society’s needs.

  • Early 20th Century

    The first hydroelectric power plant was built in 1882 in Appleton, Wisconsin. It marked a significant milestone in harnessing renewable energy from flowing water.

  • 1950s

    The development of photovoltaic (PV) cells in the 1950s laid the foundation for solar energy systems. Bell Labs produced the first practical solar cell in 1954, which would kickstart a revolution that powers solar panels even today!

  • 1970s 

    The oil crisis of the 1970s heightened awareness about the limitations of fossil fuels. This was the key factor in driving research into alternative energy sources, including wind and solar, which would prove to be the origin of Renewable Energy Systems.

  • 1990s 

    The 1990s witnessed significant global innovation, adoption and investments in renewable energy, with Germany introducing feed-in tariffs to incentivize solar power adoption. Moreover, advancements in wind turbine technology in the late 1980s had increased the efficiency and viability of wind power. This led to the establishment of large-scale wind and solar farms in the 90s in several European nations.

  • Early 2000s

    Advancements in solar technology, wind turbines and renewable energy sources marked the rise of RES in the early 2000s. Solar and wind energy achieved parity in several regions of the world, becoming cost-competitive with conventional sources of energy.

With several breakthroughs in Renewable Energy Systems, we expect it to revolutionize the global energy supply chain. Soon, we may see the integration of renewable sources into the traditional energy grid, enhancing its reliability and scalability.

So, what types of Renewable Energy Systems could be integrated into the current energy grid, you ask?
 

Types Of Renewable Energy Systems


There are different types of Renewable Energy Systems, depending on the source of power. Here are the most common ones:
 

  • Solar energy

    Is the most abundant energy resource on the planet. After all, the rate at which solar energy is intercepted by the Earth is roughly 10,000x the rate at which we consume energy. While we have not fully harnessed the sun’s energy, solar technologies can deliver heat, cooling, natural lighting, electricity, power, etc. by converting sunlight into electrical energy either through photovoltaic panels or through mirrors that concentrate solar radiation. As the cost of manufacturing solar panels has dropped significantly in the last decade, they have become the cheapest form of renewable electricity.

  • Wind energy

    harnesses the kinetic energy of flowing air using large wind turbines that can be located on land (onshore) or in the sea (offshore). Wind energy has evolved successfully thanks to taller turbines and larger rotor diameters, leading to the optimal production of electricity. Although wind energy has limitations, its potential electricity generation capacity exceeds global electricity production at the moment.

  • Geothermal energy

    taps into thermal energy from the Earth’s core via geothermal reservoirs and wells. The reservoirs that are naturally hot enough and permeable are called hydrothermal reservoirs, whereas reservoirs that are sufficiently hot but improved upon by hydraulics are called enhanced geothermal systems. The high-temperature fluids within the reservoirs are extracted to the surface and used to generate electricity, a process that has been in practice for over 100 years.

  • Hydropower

    leverages the potential and kinetic energy of water moving from a higher to a lower height. For instance, reservoir hydropower plants rely on water stored in a reservoir at an elevation, while run-of-river hydropower plants generate energy from the flow of rivers. Hydropower reservoirs are often built for irrigation, drought control, etc. but currently are the largest sources of renewable electricity.

  • Bioenergy

    uses a variety of organic materials (biomass) for heat and power production. Most biomass is used in rural areas for cooking, lighting and heating. However, modern biomass systems can burn crops, agricultural residues, various organic wastes, etc., for energy. While there are some greenhouse gas emissions, bioenergy is much cleaner than burning fossil fuels.


No matter which type of Renewable Energy System you look at, there are some inherent benefits. Want to know what they are? Scroll on!
 

Advantages Of Renewable Energy Systems


There are several reasons why harnessing renewable energy sources through Renewable Energy Systems is so critical for our future. Here are some of the top benefits of doing so:
 

  • Renewable Energy Generates No Emissions

    Generating electricity from fossil fuels leads to harmful emissions. In the United States alone, fossil fuel-generated electricity accounts for 27% of greenhouse gas emissions. Yet, renewable energy has an environmental benefit as electricity generated using RES has no emissions or air pollution.

  • Renewable Energy Lowers Your Carbon Footprint

    Everyday decisions can add up and contribute to lowering our carbon footprint (a metric used to calculate environmental impact). Using energy created from renewable energy sources lowers the carbon footprint by “offsetting” or replacing the would-be fossil fuel emissions with zero-emissions energy consumption.

  • Renewable Energy Reduces Harmful Air Pollutants

    When fossil fuels are used to create electricity, they emit dangerous greenhouse gases, leading to smog and acid rain. This can cause a variety of health problems, including coughing, throat irritation, reduced lung function and damage to lung tissues. As renewable energy sources do not release such toxins when generating electricity, they lower air pollution in urban areas. 

  • Renewable Energy Uses Less Water

    Almost all energy generation needs water at some point in the process. Traditional electricity produced from coal, natural gas or nuclear energy is generated by heating water to create steam that turns turbines. Yet, wind and solar energy do not need any water to generate electricity.

  • Renewable Energy Benefits the Economy

    Among the factors driving the adoption of RES is the fact that the price of creating clean energy is dropping quickly and the price of clean electricity itself. This will lead to further demand for clean electricity and increased investments in the technology. Moreover, government policies are reducing the cost of renewable energy resources with tax credits, for instance, for installing solar panels.


Thus, Renewable Energy Systems are quickly becoming the favorites for many industries with their many benefits. However, the biggest benefit is that these systems will only improve in the future!

TechDogs-"What’s The Future Of Renewable Energy Systems?"-"A GIF Of A Clean And Green City Using RES"
The emerging trends in the renewable energy sector can be summarized as the 3 Ds: Digitalization, Decarbonization and Decentralization

Carbon emissions surged exponentially during the Industrial Revolution, at almost 150x than they were in 1850. This alarming rise in emissions underscores the need for change. RES will play a pivotal role in enabling the transition to decarbonization, that is clean energy through innovation, research and development of clean energy.  Also, the traditional centralized energy model, dependent on fossil fuels, has created a monopolistic and fragile energy supply infrastructure. The move towards decentralization is based on the idea of hybrid microgrids that draw from solar, thermal, hydro, wind, and even hydrogen energy to deliver a mix of renewable energy. Finally, with major leaps in AI, robotics and other digital tools, we stand at the cusp of an energy transformation, as digitization will offer a range of possibilities. Think of real-time energy demand management and enhanced grid optimization along with carbon footprint reduction – that sounds like the future we saw at Technoland, right?
 

Wrapping It Up


The facts are clear – current energy generation methods will fall short of the consumption demand of the future. As we scale our energy infrastructure, we need to invest in Renewable Energy Systems to create more sustainable and effective energy grids. By integrating renewable energy sources into our existing electricity and power-generation units, we can not only cut costs, improve energy supply chains and reduce our carbon footprint but also do so in a way that RES-pects the environment.

So, are you ready for the clean energy revolution? Renewable Energy Systems certainly are!
