When the world is faced with severe environmental problems. Let’s know the various alternative energy especially solar energy that will help the world reduce pollution and the impact of global warming. It has become an alternative energy that is rapidly increasing in popularity in various countries around the world, including Thailand.

What are the alternative energy sources?

In 2020, more than 7,468 terawatts of renewable energy were used to generate electricity worldwide. There are five types of alternative energy that are used

1) Hydro power (Hydro) is an alternative energy that is used to generate electricity. (Hydroelectricity) as much as 59%. The power of water flows from rivers, lakes, dams to spin turbines and generators in hydroelectric power plants.

2) Wind energy: There are both onshore wind and offshore wind, producing energy with wind turbines and has been growing in popularity. We will see pictures of windmills in many countries. Wind power is used to generate electricity, accounting for 21% of total alternative energy.

3) Solar energy that converts solar energy directly into electricity or thermal energy. 11% of the world's electricity generated from renewable energy comes from solar energy.

4) Bio Energy, the use of waste from living things such as organic waste to ferment to decompose without oxygen. will get methane as a type of fuel Bioenergy is used to generate electricity, accounting for 8% of the total alternative energy.

5) Geothermal is the thermal energy stored beneath the earth's surface by the heat generated inside the Earth mainly due to the decay of long half-life radioactive substances such as uranium, thorium and potassium. that accumulates in the Earth's crust, 1% of the electricity generated from renewable energy comes from geothermal energy.

How interesting are solar cells?

Recently, Solar energy is widely used all over the world and become the fastest growing alternative energy technology. Since it was invented in 1954, especially photovoltaic technology or what we call photovoltaic that converts sunlight into electricity. Solar power has many advantages compared to other alternatives, such as solar cells requiring less maintenance than wind turbines. The production cost is less than the hydropower required to build the entire dam, does not cause noise and environmental changes. Importantly, solar cells can generate electricity at all levels. Since the production of electricity for commercial use until producing electricity for use in households in general houses can install solar panels on the roof. Generate electricity for use in the home.

According to data in 2021, global solar power generation capacity exceeds 700,000 megawatts, with the top five producing countries being China, the United States, Japan, Germany and India, which account for 68.6% of the total output of the five countries. of global production capacity* in Thailand It has a capacity of solar cells at 2,988 megawatts, ranked 26th. It will be an important source of energy for the world in the future.

For those who are interested in installing solar panels to generate electricity for use in the home to help reduce electricity bills. With a rising trend in the future, SCB has partnered with solar experts to offer special discounts to SCB customers, especially more details here (https://www.scb.co.th/th/personal-banking/promotions/other-services/solar-rooftop.htm).
