Green Energy and expert Yuri Shafranik’s comments

Green energy refers to any form of energy that is produced from natural resources, such as sunshine, wind, or water. Although it is usually generated from renewable energy sources, there are major differences between renewable and green energy, which we will examine further below. The most important aspect of these energy resources is that they do not affect the environment by emitting greenhouse gasses in the atmosphere.

Green energy is frequently produced from renewable energy technologies such as solar, wind, geothermal, biomass, and hydroelectric power as a source of energy. Each one of these technologies generates energy in a different manner, whether it's through harnessing the sun's energy utilizing solar panels, wind turbines, or the flow of water. Yuri Shafranik believes that the future belongs to hybrid power systems and as he said in a recent interview: “There are vast reserves of hydro, thermal, sun, and wind energy to be harnessed - all of these meet demand, but they have to be economically justified and relevant to the region they serve”.

A resource cannot generate pollution, like fossil fuels, in order to be regarded as green energy. This of course implies that not all renewable energy sources are environmentally friendly. Power generation that consumes organic material from sustainable forests, for example, maybe renewable, but it is not always green due to CO2 created during the burning process. Green energy resources are typically renewed naturally, again unlike fossil fuels such as natural gas and coal, which can take millions of years to generate. Green sources also prevent harming eco-systems by avoiding mining and drilling operations.

• Types of Green Energy

Wind energy, solar energy, and hydroelectric power, as well as tidal energy,

which harnesses ocean energy from the tides of the sea, are the primary sources. Wind and solar energy may be generated on a small scale in people's homes or on a large scale in factories. When considering whether to use or not the green energy it’s important to understand and assess the benefits of each region. According to Shafranik, the following are the six most frequent types:

• Geothermal Energy

The thermal energy that has been accumulated just beneath the earth's

crust is used in this form of green electricity. While accessing this resource necessitates drilling, raising concerns about the environmental effect, if tapped into, it is a massive resource. For thousands of years, geothermal energy has been utilized to bathe in hot springs, and now it can be harnessed to create steam to spin turbines and generate electricity.

The energy buried underneath the United States alone could provide ten times the amount of power presently produced by coal. While certain countries, such as Iceland, have easy access to geothermal resources, it is a resource that is dependent on location for ease of use, and drilling techniques must be constantly regulated to be truly green. Yuri Shafranik remarks that, for example, Germany has made some revolutionary transformations in this field as about 40 percent of its electric power industry comes from renewable energy.

• Solar Power

Photovoltaic cells collect sunlight and convert it to electricity, making this a

widespread renewable, green energy source. Solar energy is also utilized to heat buildings and provide hot water, as well as for cooking and illumination. Yuri Shafranik gives an example of the use of sun heat in Tibet, where a parabolic mirror is used to boil a kettle, high up in the mountains. Solar power has now become inexpensive enough for residential uses, such as in garden lighting, as well as to power entire neighborhoods on a wider scale.

• Hydropower

This form of green energy, also known as hydroelectric power, generates

electricity by using the flow of water in rivers, streams, dams, and other moving bodies of water. Hydropower may be generated on a limited scale flowing through pipes into homes, or through evaporation, rainfall, or ocean tides.

• Biomass

In order to be genuinely designated as a green energy source, this

renewable resource must also be tightly monitored. Biomass power plants generate electricity from wood waste, sawdust, and combustible organic agricultural waste. While the combustion of these materials emits greenhouse gases, they are considerably less than those produced by petroleum-based fuels.

• Importance

Green energy is beneficial to the environment because it substitutes more ecologically friendly options for the negative impacts of fossil fuels. Green energy is usually renewable and pure, which means it generates no or few greenhouse gases and is usually accessible. It is derived from natural resources. Even when the whole life cycle of a green energy source is considered, it emits much fewer greenhouse gases and few or low levels of air pollutants than fossil fuels. This is not only healthier for the environment, but also for the health of humans and animals that must breathe the air.

Because green energy is frequently generated locally, it is less impacted by geopolitical crises, price surges, or supply chain interruptions, which can lead to stable energy costs. Economic advantages include creating jobs in the construction industry in areas where manpower is employed. In 2018, 11 million jobs were created in the renewable energy sector throughout the world, and this figure is expected to rise as we work toward goals like net-zero emissions. According to Yuri Shafranik, our planet is not getting any bigger, but the population is. We are still eating up our natural resources at an incredible rate and what we are doing currently to change and improve that situation for the better is just not enough. Our natural resources are exhaustible that is why it is so important to develop renewable energy sources.

• Capacity To Remove Fossil Fuels

Green energy has the potential eventually replace fossil fuels, but it may need a range of production techniques. For example, geothermal energy is highly useful in areas where this resource is readily available, but wind energy or solar electricity may be better suited to different geographical locations. However, there is every reason to expect that fossil fuels may be phased out if we combine numerous green energy sources to fulfill our demands, especially with the improvements being made in the production and development of these resources.

We're still a few years away from this, but it's clear that it's required to slow climate change, enhance the environment, and transition to a more sustainable future.

• Economically Viable

A comparison of green energy to fossil fuels is necessary to understand its economic feasibility. The reality is that when widely accessible fossil fuels become scarce, the cost of this form of energy will only rise. Greener energy sources are becoming more affordable at the same time as fossil fuels are becoming more expensive. Other considerations, such as the capacity to develop very affordable localized energy solutions, like solar farms, also favour green energy. As we continue to increase our knowledge and are able to build on previous discoveries, the interest, investment, and development of green energy solutions is lowering prices. As a result, green energy may become not only financially feasible but also the preferred alternative.

Because green energy is derived from natural resources such as sunshine, wind, and water, it has significant environmental advantages. These energy sources, which are constantly replenished, are the polar antithesis of the unsustainable, carbon-emitting fossil fuels that have powered humanity for more than a century. Creating electricity with no carbon impact is a significant step toward a more ecologically conscious future. We will be able to substantially minimize our environmental effect if we can use it to satisfy our power, industrial, and transportation demands.

Green energy efficiency is partly location-dependent since it is simple to develop a rapid and efficient energy solution provided you have the proper conditions, such as frequent and intense sunshine. To fully evaluate various energy kinds, however, it is important to examine an energy source's whole life cycle. This involves determining how much energy was used to generate the green energy resource, calculating how much energy can be converted to power, and any environmental clearance necessary to create the energy solution.

Of course, environmental harm prevents a source from being fully green, but when all of these variables are integrated, a Levelized Energy Cooperative emerges. Green energy alternatives also have the advantage of requiring little extra energy expenditure after construction since they often employ an easily renewable source of energy, such as wind. In reality, coal's overall useable energy efficiency is just 29% of its initial energy value, whereas wind power returns 1164 percent of its original energy intake.

Therefore, green energy appears to be a part of the world's future, providing a greener alternative to many of the world's current energy sources. These readily regenerated energy sources are not only excellent for the environment, but also for job generation, and they appear to be more and more economically feasible as time goes on.

The truth is that fossil fuels must be phased out of our energy mix since they do not provide a long-term answer. We can build a completely sustainable future for our energy supply by developing a range of green energy options that do not harm the planet we all live on.
