It is a grim fact that the world’s natural resources are depleting at a burgeoning rate. With the demand for energy increasing daily to full fill the needs of the industrial sector, that day is not far when we will be exhausted out of all our resources.

Therefore, environmentalists urge people to save precious resources and find an alternate means to find renewable energy sources. With the advancement in science and technology, people are finding ways to save energy and eliminate waste by switching to renewable energy. They are adjusting to the growing need for utilizing cost-effective forms of sustainable energy solutions.

Technological advancements are promoting the use of energy efficiently, without compromising on functionality. After all, light-emitting diode – LED bulbs produce the same amount of light, but with less power. Well, 2020 is bringing more energy-efficient technologies, geothermal, biomass, marine solar, by using renewable sources of energy – wind and sunlight.

Following are the famous five energy-efficient technologies in 2020:

1. Marine Solar Panels

Renewable energy uses sunlight and wind, and marine solar panels might sound a little confusing to everyone. They also use sunlight to produce energy, but these are not the roof solar panels. As the name suggests, it harnesses energy from the sun and uses it to power the boats. It efficiently recharges the batteries of boats or acts as a backup in case the ship runs short of fuel.

Usually, you would come across flexible panels that can be bent or curved to fit the size of the boat, especially for the boats which don’t have space for large panels. Otherwise, standard panels come with aluminum backing, protecting the boat from harsh weather conditions. Alongside saving you fuel costs, it is an efficient way of using energy while protecting marine life from pollution.

2. Solar Panels

Even though solar panels might not be the newest invention, it is the most efficient way of saving energy in homes. If you live near Sydney, then you can easily find a reputable solar PV and solar battery specialist, these professional companies are expert in providing a 5kw solar system in Sydney for residential use.

Furthermore, in 2020, technology has brought machine learning to the use of solar panels. These panels adapt to your energy needs and evolve accordingly.  Moreover, scientists have come up with nanoparticles for solar cells that are less expensive, reducing the costs of solar panels. Similarly, they have discovered a new material would convert sunlight into energy more efficiently. Electricity is more like a ‘use it or lose it’ resource when produced by solar panels because they can’t store energy. In 2020, the molten salt technology in solar panels all you to save electricity and use it when sunlight is not available.

3. Green Hydrogen

Besides being a colorless gas, hydrogen is free from toxins. Surprisingly, there are no hydrogen deposits on earth, and it is available after extraction from different chemical compounds. If solar panels produce electric current, it can generate green hydrogen without any harmful emissions. It can decarbonize industrial processes, gas heating, and heavy transport.

Moreover, it works as an alternative to fossil fuel to remove harmful emissions from the air, helping people move towards a clean and healthy environment. It is time for industries to show responsibility towards the environment by using green hydrogen, instead of continuing to pollute the environment. It is also providing a solution for enterprises that produce heaps of chemical waste.

4. Grid-Scale Battery Storage

Solar panels provide electricity only when the sun is out shining brightly. Hence, it does not generate energy at night or during rainy seasons, which is not allowing people to make the most out of it. Grid storage enables people to store energy on a large scale within the electrical power grid. It works by storing electricity from networks and solar panels, discharging it at the time when you need it.

Previously, storage capacities were limited to 4.9GW, but in 2020, you can store energy up to 20GW. Apart from making electricity readily available, it helps with electricity load management, while maintaining quality power supply. Thus, allowing you to enjoy uninterruptable power supply at all times while ensuring efficient use of energy.

5. Electric Vehicles

The news about electric vehicles is out for a few years. In 2020, you can spot approximately 5.1 million electric cars on roads, and this figure will increase significantly in the coming years. These cars are running on batteries instead of fuel, making them cheaper due to low running costs. The production process of these cars incorporates all the eco-friendly techniques.

Companies are using recycled material for manufacturing cars, while the padding consists of bio-based materials. They use empty plastic bottles, plastic bags, damaged home appliances, making the most out of available resources. Unlike cars operating on fuel, electric vehicles don’t emit greenhouse gases and air pollutants, helping people move towards a healthy environment. At the same time, you can use renewable energy to charge your electric car, further reducing greenhouse gas emissions.


People have taken a wise step to move towards renewable energy, leaving sufficient resources for the upcoming generations. The availability of products like LED bulbs, carbon fight cloth dryers, and magnetic refrigerators are encouraging the efficient use of energy. With these technological advances, you can also adopt green practices by merely choosing to save energy and use renewable energy sources for your home.
