The world’s thirst for energy is ever-growing. As the global population increases, more and more fossil fuels are being consumed. In 2022 alone, the US used about 4 trillion kilowatt-hours, and the need is only going to increase.
However, the need for fossil fuel energy doesn’t necessarily need to increase.
The world has already been experiencing the impact of climate change. From droughts to floods to more serious problems like the spread of infectious diseases, we’re all affected by climate change. Because of this, it’s time to take action.
Keep on reading as we take a look at clean energy solutions to combat climate change:
Solar Energy
Solar energy is a renewable energy that does not need conventional fuel. It produces no pollution or emissions when consumed.
It is generally collected using photovoltaic solar cells. This converts sunlight into electricity. This electricity can then power homes, businesses, and entire communities.
It is becoming popular globally as people look for ways to become more sustainable. It is also durable and has low maintenance costs.
Solar energy is also safer than nuclear or coal-burning energy sources. The development of solar energy has made positive strides in the global clean energy movement.
Solar energy continues to provide a clean, renewable energy source for decades to come. Here are the different technologies that could harness solar energy:
Photovoltaics
This type of solar technology uses sunlight to generate electricity. This can then be in storage or used as needed. It is one of the most efficient ways to harness the energy of the sun.
Photovoltaics come in different types and sizes. It can be monocrystalline, polycrystalline, amorphous silicon, and hybrid panels.
Monocrystalline is from single-crystal silicon. It is the most efficient form of photovoltaics.
Polycrystalline is from many crystalline silicon pieces fused. Amorphous silicon is thin-film solar cells with low efficiency.
Finally, there are hybrid panels. This combines the advantages of monocrystalline and thin-film technologies.
These photovoltaics are typically used in solar panels in Charlotte to generate electricity for homes.
Solar Thermal Technologies
Solar thermal technologies harness energy from the sun to directly convert to heat. These technologies are useful in a variety of ways.
They can be used with water heating systems for commercial and residential buildings. People use this in applications to produce electricity and in industrial processes that require heat.
Solar thermal technologies capture the sun’s heat by using devices. This includes flat-plate collectors or concentrating collectors to absorb the energy and convert it to heat.
Solar thermal systems use a variety of techniques to store heat. It converts the heat to electricity and transfers it to an application such as a water heater or industrial process.
Solar Thermal Energy Storage (STES) Systems
Solar Thermal Energy Storage Systems (STES) is a type of solar thermal energy technology. It collects, stores, and distributes solar energy to generate electricity. STES systems use a combination of mirrors and a storage tank to capture the sun’s heat.
These systems can provide energy for both residential and commercial purposes. They can also provide energy to remote community locations. So places that might not be well served by traditional electricity grids have it as a good option.
STES systems need minimal maintenance and can continue providing energy long after initial costs. They are also often less expensive. They require less time to install than other solar energy technologies.
Solar Energy Towers
Solar energy towers are an emerging solar technology. They are also known as central tower receiver systems.
This uses a combination of thousands of reflectors to concentrate the sun’s energy onto a single point and generate electricity. The energy is then captured and stored before the grid absorbs it.
The technology can track the sun’s movement. This ensures high levels of efficiency and reliable energy production.
Solar energy towers are particularly useful for remote areas due to their scalability.
Wind Energy
Clean energy solutions include wind energy. This is a renewable source of energy obtained through wind turbines. Wind energy can generate electricity, power ships, or create mechanical power and pump water.
Wind turbines convert the kinetic energy of wind into electricity. These turbines vary in size, from large commercial turbines to relatively small micro-turbines. Large-scale wind turbines are often combined, forming a wind farm.
Wind energy is an amazing clean energy solution. It produces electricity without emitting any air pollutants or other hazardous wastes. It is efficient and can reduce dependency on fossil fuels.
Compared to both nuclear and coal-fired power plants, wind turbines present no risk to humans or the environment. They also contribute to reducing the amount of pollution in the atmosphere.
Not to mention that wind energy projects have quick installation times. They can provide reliable energy and electricity in areas with high winds and open spaces.
Hydroelectricity
Hydroelectric power is a clean energy solution used to generate electricity from the movement of water. This resource is an ecologically friendly option to generate power and is a renewable form of energy. They use specialized turbines to convert the kinetic energy of flowing water into electricity.
Hydropower systems have many advantages compared to other methods of generating electricity. It is typically reliable, emissions-free, and has no direct waste products. This clean energy solution also helps to cut the environmental impact of electricity generation.
While it only makes up a small portion of electricity production in the US, hydroelectricity is a promising clean energy solution. It offers long-term potential for both residential and industrial energy consumers.
The source of hydroelectric energy is also diverse. They include the following:
Reservoir-Based Hydroelectricity
Reservoir-based hydroelectricity is the most common form, where a large body of water is in storage behind a dam. This creates a pool of water that people can suspend to generate electricity when the energy demand is highest.
The water is then released through turbines to generate electricity. It can generate electricity on a regular schedule. This technology helps ensure that stable sources of energy are available during peak hours.
Reservoir-based hydroelectricity also helps conserve natural water resources. This can contribute to flood control.
Run-of-River Hydroelectricity
Run-of-river hydroelectricity uses the natural flow of the river to generate power. It does not require a large dam or reservoir but instead operates at existing river flows. It is a more economical and less damaging form of harnessing hydroelectric power.
A diversion dam, or other type of structure, is along the river to capture a portion of the flow. As water passes through the diversion structure, it flows through a turbine. This turns into a generator which produces electricity.
This type of technology allows for hydroelectric power to be generated in a low-cost and low-impact manner. At the same time, it is reliable as river levels tend to remain steady throughout the year. And because the use of water is not obstructed, downstream river levels can maintain their natural course.
It is not great for large-scale power production but is ideal for smaller scale. It’s excellent for areas where traditional hydroelectric technologies are not applicable.
Geothermal Energy
Geothermal energy is a renewable form of energy that has the potential in a wide variety of ways as a clean energy source. It utilizes the natural heat stored within the earth’s core to generate electricity. It emits virtually no carbon dioxide or other greenhouse gases.
Potentially, geothermal energy could power everything from residential homes to commercial businesses. This could help to reduce air pollution levels while still providing a reliable, safe source of energy.
Since geothermal energy comes from renewable energy stored underground, its supply will never run out. The ground will always exist, and so is its heat. This makes it a reliable, long-term, clean energy solution.
Direct-Use Technology
Direct-use technology utilizes heated groundwater from the ground without any power-producing process. This technology is typically found in commercial, industrial, and residential contexts. It can heat water, buildings, and other applications that need temperature control, such as greenhouses and spas.
Although widely used, direct-use technology still has quite a few drawbacks. This includes fluctuations in temperature and silting or scaling of interior pipes. It also includes limited access to suitable geothermal resources.
Its potential, however, has not been fully realized. It can still be an excellent option to supplement other renewable energy sources.
Geothermal Power Plants
Geothermal power plants are one of the many different types of geothermal technologies. The type of geothermal technology employed varies depending on the region and geological features of the earth’s crust.
Currently, the most commonly used type of geothermal plant is the dry steam power plant. This makes use of naturally occurring pockets of steam from deep underground.
Another type of geothermal plant is the Binary cycle power plant. This uses a two-stage process to generate electricity and is suitable for lower-temperature water sources.
Additionally, enhanced geothermal systems are also looked into as an alternative way to extract energy from the earth. Each type of this technology has advantages and disadvantages and varying levels of efficiency. Nevertheless, all provide a means of clean, renewable energy.
Bioenergy and Biomass
Bioenergy and biomass are clean energy solutions that make use of organic matter, such as wood, waste, or crops, to create energy. They create energy that emits little to no pollution or greenhouse gases. This is because the energy comes from naturally occurring, renewable sources and not from burning fossil fuels.
Bioenergy and biomass can generate electricity, produce heat, or power vehicles. For example, the burning of wood pellets to generate electricity is a common use of bioenergy. Other forms of biomass, such as plant-based oils or gases, are raw materials that can turn into transportation fuels.
Additionally, bioenergy can create a variety of biofuels, including ethanol and biodiesel. By using these methods, nations can reduce their dependence on fossil fuels and reduce their carbon footprints.
Here are more detailed information on how these types of energy are used:
Anaerobic Digestion
Anaerobic digestion is the process of breaking down organic matter in the absence of oxygen to produce biogas. This is then used as a substitute for fossil fuels.
This technology releases methane, carbon dioxide, and other gases in a controlled way. This reduces the environmental impacts of traditional fossil fuels.
Pyrolysis
Pyrolysis is the thermal decomposition of biomass. It can be a fast or slow process, depending on the desired results.
Fast pyrolysis is best for producing liquid biofuel from biomass. On the other hand, slow pyrolysis produces more charcoal and biochar.
On an industrial level, pyrolysis plants can convert large quantities of organic matter. This includes plant-based biomass into energy sources such as biogas and heat. Biomass can also convert into other useful products such as liquids, waxes, and charcoals.
Biodiesel
Biodiesel can come from a variety of biomass sources. These sources can include vegetable oil, animal fat, and even used cooking oil. They can be both economically and environmentally friendly.
It also has many benefits. This includes offering emissions reductions when compared to traditional diesel fuels.
Torrefaction
Torrefaction produces bioelectricity by creating compressed gas, liquid, and solid fuels. These call all burn for the energy production process.
Some examples of biomass sources that this technology can be used for include rice straws and palm shells. People also use olive kernels, wood pellets, cotton cores, and palm fronds.
Torrefaction also can convert waste biomass into energy. This can range from animal waste, plant waste, and agricultural crop waste, including bagasse and palm oil.
To produce bio-electricity, the biomass undergoes a process in a thermal reactor. This can produce a solid, charcoal-like product as well as a liquefied fuel.
