Nowadays, attention is drawn towards sustainable living and environmental protection more than ever. An important aspect of this dialogue is understanding the classification of resources into renewable and non-renewable resources. Renewable resources are those that can be replenished naturally over periods of time and thus provide ways of solving the growing demands of our society without exhausting the earth’s resources. On the other hand, non-renewable resources are limited and may run out.
In this series, we will analyze the reasons why renewable resources are gaining popularity, sift through the types available and their benefits, and some that may rejuvenate future levels of reliance on resources. Some of their examples and the renewable nature of the resources will end this post.
What Are Renewable Resources?
Renewable resources are said to be natural materials and energy that have the capacity to be naturally restored over an acceptable time frame. These resources are indeed being replaced either biologically or otherwise in natural cycles, hence set aside for the coming people. Unlike fossil fuels, namely coal, oil, and gas, which take millions of years to be formed, renewable resources are caused to replenish constantly by environmental factors, such as sunlight, wind, water cycle as well as plant growth.
Examples of renewable resources include solar energy, wind energy, biomass, geothermal energy, and hydropower. Such resources not only reassess the risk of depleting exhaustible resources but also help in doing away with the environmentally damaging processes of energy generation such as greenhouse effluent emissions.
Importance Of Renewable Resources
The next question is, why are these renewable resources so significant? Firstly, they provide a new reliable energy source to the increasing world populations. The world is on the brink of facing, if not facing already, an energy crisis for the sole reason of growing energy demand and depletion of reserves of non-renewable resources such as coal and oil fuels.
Secondly, the renewable resources assist in reducing climate variability. Among the many activities that aggravate climate change, the use of fossil fuels is one of the largest since these products are the highest source of greenhouse gas emissions. This will help to cut down carbon emissions and prevent the adverse effects of climate changes through global warming.
Third, renewable energy resources cater for energy security. The supply of fossil fuels is more geographically concentrated causing more geopolitical disputes and price fluctuations. Renewable energy sources on the other hand, have a more uniform distribution over the globe leading to less geopolitical and market tensions regarding energy supplies.
Some Important Types of Renewable Resources
Let visit some of the most common alternative energy forms, the sources from which they originate and their applicability in the present world.
1. Solar Energy
Out of the many forms of renewable energy one of the key forms often hailed as the most ubiquitous is solar energy. It makes use of the sun’s energy which is converted into electricity or heat energy by the use of solar panels or other solar thermal equipment. The sun is the most reliable source of energy on earth since there is no limit to its power.
So, how can solar energy be used?
Photovoltaics: These will involve directly converting solar energy to electrical energy through solar cells (panels).
Solar power: In these systems heat is harnessed from the sun and is either used to produce power or heat up spaces heating buildings.
The main reason as to why solar is viable is because of how widely it can be used, with very little land and human interference and no production of any gas pollutants within the operation phase. This can be done at smaller scale, such as homes, or at bigger scales in solar farms. There are however some drawbacks of solar energy for instance its supply is affected by sunlight and other factors such as the weather and the continuous use of solar energy is subject to the existence of batteries.
2. Wind Energy
Wind energy is another key renewable energy source. The kinetic energy of wind is harnessed by wind turbines and converted into electrical energy. Both onshore and offshore wind farms are becoming very popular in many countries especially in areas that have strong and constant winds.
Wind energy is a pure source of energy which is clean and inexhaustible. It is fully expandable, making it possible to install small turbines for individual homes and businesses as well as large wind farms designed to serve entire local communities. As with solar energy, wind energy also has its challenges since the availability of wind is never constant, this is why there are often supplementary energy storage or back up systems available to guarantee that energy is always accessible.
3. Hydropower
Often known as water power, Hydropower is also among the earliest forms of renewable energy and remains relevant up to this day. Energy is produced from harnessing the flow of water from either a river or a dam to rotate turbines that produce energy. Hydroelectric generation can be developed as massive hydroelectric power stations providing high levels of energy often for an entire area.
Hydropower is a renewable energy form due to the fact that water can be replenished through natural processes like precipitation and evaporation. Nonetheless, there are a few downsides that are shown particularly with large reservoirs, such as the flooding of villages and habitats within valleys or changing the environmental flow of rivers and affecting riverine communities. Through proper methods like diversion dams, the minimizing impact of run-of-river hydropower programs is safer.
4. Geothermal Energy
Geothermal energy technology uses heat that is captured in the interior of the earth to generate electricity or heat water. It is obtained by utilizing hot water or steam reservoirs found in the outer crust of the earth. Geothermal heat extraction does not deplete the resource because it is renewable.
Geothermal energy resource does not depend on wind or sunlight as wind and solar do. Therefore, geothermal electricity is steady and less vulnerable to environmental factors. It produces little or no harmful gases than other renewable energies. Geothermal power plants can also run disregard weather and time which gives them an upper hand over peak load plants. There are disadvantages, however, in that geothermal energy is highly geographical; one needs to be situated in areas with geothermal action such as volcanoes or tectonic plate boundaries
5. Biomass
Biomass energy sources may be in different forms but is derived mainly from renewable or organic matter like biotechnology, animal or plants waste. These resources can be used for direct heating, or processed into bio-fuels or bio-energy such as ethanol and biodiesel respectively. Though they cause degradation, biomass fuels are not harmful as long as they are obtained from responsible practices where trees and crops are replaced and waste is handled.
Biomass is an energy source that can be transformed into a range of applications such as power, heat, and transport fuels. It also has the benefit of recovering by-product waste materials that would otherwise be left untouched. Facing the same challenges, there is land degradation, deforestation and land use, and biomass burning, which results in carbon emissions, which have to be addressed if this is to be more sustainable.
Other forms of Renewable Resources
Biosphere and medium renewable meteorological energy resources such as thermal solar, wind, hydropower, biomass and geothermal energy are most prevalent. There are a few others, however, that are new methods that are being developed in order to utilize renewable sources of energy.
1. Ocean Energy
Ocean energy encompasses tidal and wave energy which makes use of the kinetic energy of water to produce electricity. Tidal energy makes use of the changing sea levels while wave energy uses the energy in the waves. Although it is not yet commercially widespread, ocean energy has a great potential, especially in areas near the coast.
2. Hydrogen
Hydrogen is mostly seen not as a fuel and energy but as an energy carrier. If the making of hydrogen requires intuitive energy (green hydrogen), this has optimal advantages. Hydrogen can have many applications such as; transportation, industrial use, and generation of clean electricity without producing any gaseous emissions. But it is still in the development stage how to make hydrogen and use it effectively for progress.
Challenges of Renewable Resources
In as much this seems like an ideal approach, there are barriers linked to enhanced renewable resources.
Intermittency
One of the most cited challenges is intermittency. Solar and wind energy are not always in supply or present at all times as the sun is not always shining while the wind may not be blowing all the time. This variability may create a challenge in maintaining the energy supply at a desired and consistent level in the absence of energy storage measures or standby power sources.
Energy Storage
Therefore, due to intermittence, there is a need for proper energy storage systems to encompass all the renewable technologies. There are growing technologies such as batteries, pumped hydro storage, and hydrogen energy storage, which are intended to harness excess energy when it is produced and release it when the production of renewable energy is not at its peak.
Initial Investment
The only drawback is the great cost of making the necessary investments for a fully-fledged infrastructure such as solar panels, wind turbines and geothermal plants. However, it is expected that as these affordable technologies get better and cheap, anyway, the renewable energy would be within reach for all.
The Future of Renewable Resources
Renewable energy sources are the future of energy. Owing to development and improvements in technology, the renewable resources are becoming efficient, dependable, and inexpensive. All over the globe, governments appreciate the need for the use of renewable energy in mitigating climate change, and are providing the necessary policies.
Moreover, a new generation of storage technologies will resolve this issue such that supply can meet demand off peak times when intermittent occur. There are already emerging trends for the global energy transition since most countries have set targets for the adoption of renewable energy.
Conclusion
The world’s future cannot be built without the use of renewable resources. This is because the energy generated by solar, wind, water, and earth can help us to decrease our usefulness of dwindling assets, cut down emission of greenhouse gases, and advance the preservation of nature. However, the barriers are only temporary and with the further advances and integration of renewable energy technologies, the attention-driven change will lead to a more efficient and cleaner energy system.
To sum up, renewable resources include solar, wind, hydropower, biomass, geothermal energy which are supplemented with non-renewable sources, increasing the energy supply and also decreasing negative impact on the environment. Supporting and investing in adopting and upholding such resources, however, is one of the major developments that will enable one to avoid such risks in the future.
