Study Notes

Biomass Energy Disadvantages

Biomass energy generates large amounts of carbon dioxide, contributing to greenhouse gas emissions.
Production of biomass can be land-intensive, requiring substantial agricultural space for organic material.
Although its production can be costly, the environmental impacts are a more significant concern.

Conservation of Energy

The principle of conservation of energy asserts that energy cannot be created or destroyed, only transformed from one form to another.
This principle emphasizes the transfer and conversion of energy within closed systems.

Biomass Power Generation

Biomass energy is produced by burning organic materials, which generates heat to produce electricity.
This process utilizes the stored energy in plant matter and waste products, converting it into usable power.

Tidal/Wave Energy

Tidal and wave energy is derived from the movement of ocean tides and waves.
This renewable energy source exploits the natural motion of water bodies to generate power.

Wind Energy Sources

Wind energy primarily originates from the sunlight, which warms the Earth's surface unevenly, creating wind currents.
The Earth's rotation also contributes to wind patterns, enabling the use of turbines to harness wind energy.

Definition of Energy

Energy is defined as the ability to perform work, encompassing various forms such as kinetic, potential, thermal, and electrical energy.

Solar Energy Generation

Solar energy is generated by converting sunlight into electricity through photovoltaic cells.
This technology captures solar radiation, facilitating the generation of renewable energy without emissions.
