Whether residential, commercial, or industrial, solar technologies have emerged as a beneficial source of producing green energy solutions. Solar energy is a source of reduced utility bills in residential areas. In commercial and industrial areas, solar energy promotes a healthy environment with low or zero environmental impact and greenhouse gas emissions. Along with these benefits, sustainability and long-term savings are additional advantages that businesses get by incorporating green energy solutions.

3. Wind Energy

• 3.1 Types of Wind Turbines

There are several wind turbines used for power generation. The common types are:

• Horizontal-Axis Wind Turbines (HAWTs): HAWTs are the most common type of wind turbines that rotate on a horizontal axis. These are used for large-scale industries and farms. They have large blades that rotate when the wind blows and generate electricity.
• Vertical-Axis Wind Turbines (VAWTs): VAWTs are less common than HAWTs and their blades rotate on the vertical axis. VAWTs have been getting recognition as technology advances. It is due to their versatile nature that they can use wind from any direction to produce electricity. Like HAWTs are used for larger areas, VAWTs are used for smaller scale and urban areas.
• 3.2 Key Benefits and Applications

Wind energy is a green energy solution that can be generated onshore and offshore. Onshore wind farms are positioned on land and are widely used. Offshore wind farms are situated inside water and usually operate when wind pressure is high. Just like solar energy contributes to environmental stability, wind energy also aids in reducing greenhouse gas emissions along with promoting a cleaner and more refreshing environment to breathe in.

4. Hydropower

• 4.1 Types of Hydropower Systems
• Hydropower systems use water to produce electricity. It is a major form of renewable energy and an important source of green energy solutions. Some common types of hydropower systems are as follows:
• Conventional Dams: large-scale power plants use water reservoirs to store water. The stored water is then used by turbines and grid stations to generate electricity. Dams not only store water but can also fulfill the deficiency of power supply and are a major source of flood control.
• Run-of-River Systems: Run-of-River systems are used for small-scale purposes. They are designed to produce electricity by using a water flow from a small part of the river. These systems do not require large water reservoirs like conventional dams.
• Micro-Hydropower: As the name suggests, microhydropower plants are made for small areas. They cannot bear larger loads and generate power for local use only.
• 4.2 Key Benefits and Applications

Hydropower plants seem to be beneficial for large-scale power production. They help in providing constant energy supply and controlling floods in different areas. In rural areas, farmers opt for hydropower systems to irrigate their lands and have a balanced water supply. However, they might be a threat to aquatic life but overall they have useful advantages.

5. Geothermal Energy

• 5.1 Types of Geothermal Systems
• Geothermal Power Plants: Geothermal power plants are often located in hot areas as they use Earth’s heat to generate energy. They are designed to use Earth’s heat to form steam and use it for power generation.
• Geothermal Heat Pumps: With advanced technology, the world has discovered ways to integrate renewable energy solutions into their daily lives. Businesses with large buildings have geothermal heat pumps that control the temperature of the buildings.

Geothermal plants can be costly if you are thinking of installation. But worth the investment as it is a green energy solution and promotes the sustainability and marketability of the building.
