Renewable resources are the power of the future

The eight billion of us consume quite a lot of electricity, day in and day out. We can’t keep on burning coal to generate enough power to keep all our fridges going, we need to look at renewable resources for the near future. Let’s find out which ones we have and what their role can be.

The different types of renewable resources

In recent years, the demand for renewable resources has grown as people become more aware of the environmental and economic benefits they offer. Renewable resources are sources of energy that can be replenished naturally and sustainably over time. There are several types of renewable resources, each with its unique characteristics, advantages, and challenges. In this section, we will explore the different types of renewable resources and their potential to transform the energy landscape.

Hydroelectric Power

The use of water to create electricity is known as hydroelectricity. When water is forced through a small gap, it gains momentum and speeds up. The water then flows past a turbine, which is set in motion by the force of the water. A current is generated by this rotating turbine. Electricity is not produced by burning or consuming water; rather, the water simply flows and does its natural thing. It’s even possible to generate additional energy from the water by pumping it back uphill. That’s why you can count on always having access to fresh water.

Wind Power

The blades of a wind turbine spin in the wind, converting the kinetic energy into usable electricity. To harness the most energy from the wind, turbines are mounted on tall towers. Electricity is generated when the blades spin a shaft connected to a generator. Because wind is both abundant and costless, it makes for a fantastic renewable energy source.

Tidal Power and Wave Power

Using the motion of the water to turn a turbine is the basis of tidal power. This turbine, however, harnesses the tidal movement of the oceans and seas to generate energy, as opposed to forcing it through a small opening like a dam. Wave power, on the other hand, harnesses the energy contained within actual waves, which are primarily the result of atmospheric conditions. These two renewable sources are underutilized.

Solar Power

Solar panels collect the sun’s rays and convert them into usable electricity. To do this, photovoltaic cells are set up to convert the sun’s rays into electricity. Solar energy is the renewable energy of the future because it is sustainable. 

Geothermal Power

Geothermal power plants tap the underground reservoir of heat. In order to harness the power available from the planet’s heat, vapours or liquids must move. Imagine a hot spring where electricity is generated. In Iceland, this technique is widely used to produce electrical power.

Biomass Power

Biomass refers to the organic material derived from living organisms. Wood, crops, manure, and even some trash fall into this category. Heat is produced when the chemical energy stored in biomass is burned. This heat has the potential to power a generator. Plants can be grown to replace those that are harvested and used, making biomass a renewable resource.

Of all the renewable resources, solar is the closest to home

Solar power is one of those renewable resources that is omnipresent. The rays of sun that hit our planet are extremely powerful, they can make electrons move in a way that creates a current.

The sun is basically always there, providing us with more power than we could even consume. All we need to do is harness the light using solar panels, and we can turn that into electricity which can be stored in batteries (check here to learn how solar panels work). This way you can still use it even after the sun goes down. Thanks to improved solar cell efficiency, we can get more energy out of the sun at a growing rate. This makes solar energy such a powerful resource.

Renewable energy from the sun can be utilized on a daily basis

From solar watches to solar lanterns to outdoor solar lights, there are so many solar-powered devices on the market right now. Check out our picks for the top solar-powered gadgets:

Why are renewable resources the power of the future?

Renewable resources, such as solar, wind, hydro, geothermal, and biomass, are considered the power of the future because they offer several advantages over traditional fossil fuels.

• Sustainable: Unlike fossil fuels, which are finite and will eventually run out, renewable resources are essentially unlimited and can be replenished naturally over time.
• Environmentally friendly: Renewable energy sources emit little to no greenhouse gases or other pollutants, reducing the impact on the environment and climate change.
• Cost-effective: As technology improves and demand grows, the cost of producing renewable energy has significantly decreased, making it more competitive with traditional energy sources.
• Energy independence: Using renewable resources can reduce dependence on foreign oil and increase energy security.
• Job creation: The transition to renewable energy creates new job opportunities in areas such as manufacturing, installation, and maintenance.

Projects for community-based renewable energy

In recent years, community-based renewable energy projects have grown in popularity as more people have come to understand the advantages of renewable energy and desire to play a more active role in building a sustainable future. This section will examine some of the advantages and difficulties of community-based renewable energy projects while also looking at some global instances.

Benefits of those projects

Community-based renewable energy projects provide a number of advantages over conventional energy projects. They encourage local ownership and management, offer economic advantages, assist in lowering greenhouse gas emissions, and enhance air quality.

Types of projects

Community solar, wind, hydro, and biomass projects are just a few examples of the various Community-Based Renewable Energy Projects that are available. These initiatives may be created by local governments, cooperatives, or other organizations.

Case Study 1

Germany’s Revolution in Renewable Energy: Germany has been a pioneer in the creation of community-based renewable energy initiatives. Many of the renewable energy projects that have been developed as a result of the nation’s “Energiewende” (energy transition) program are owned and maintained by local communities.

Case Study 2

Using the Standing Rock Sioux Tribe as a case study two: A community-based wind farm that produces electricity for the homes and businesses of the Standing Rock Sioux Tribe in North Dakota has been constructed. The project brought about financial gains and lessened the tribe’s reliance on fossil fuels.

Solutions for integration & storage in the future

As we move toward a cleaner and more sustainable energy future, finding ways to integrate renewable energy sources into the grid and store extra energy has become a crucial task. Let’s examine some of the developments in technology and innovation that are being made to tackle this problem.

Grid integration of renewable energy

One of the major problems we have is integrating renewable energy into the system. Renewable energy sources make it more difficult to maintain a consistent and reliable energy supply because they depend on the weather and other factors, unlike conventional power plants that can produce an electricity stream continuously. As a result, efficient grid integration of renewable energy requires careful planning and supervision.

Battery storage

One of the most promising methods for storing extra renewable energy is battery storage. Advances in battery technology are making this storage option more efficient and affordable as demand for renewable energy keeps rising. Batteries can store energy and release it when needed, which is useful when there aren’t enough renewable energy sources available or demand is high.

Pumped hydro storage

Another form of energy storage that can be utilized to store extra renewable energy is pumped hydro storage. Water is pumped from a lower reservoir to an upper reservoir and then released back down to generate electricity as needed when there is excess energy available.

Power-to-Gas

Another cutting-edge approach is power-to-gas technology, which converts surplus renewable energy into gases like hydrogen that may be saved and utilized later. This hydrogen can be put into the gas grid to replace natural gas or utilized to power fuel cells.

Microgrids

Small-scale power grids known as microgrids can run separately from or in cooperation with the larger grid. They can include energy storage options and renewable energy sources, offering a dependable and sustainable energy supply in outlying locations or during blackouts.
