Natural resources

are components that exist in the world without the input of humans. These are diverse ranging from renewable to nonrenewable, living to nonliving, as well as tangible to intangible resources (Sawe, 2018).

natural resources

for our survival, growth, development, and progress. These include materials, water, energy, minerals, and others that can be transformed to produce benefits (Chan, 2016

Renewable natural resources

are natural resources that, after exploitation, can return to their previous stock levels by natural processes of growth or replenishment.

Solar Energy

Since earth formed, the sun has produced energy in the form of heat and light. It is considered unlimited. _____ is converted into electricity with the use of photovoltaic cells.

Wind Power

Wind is moving air created as the sun heats the earth's surface. Wind energy generates electricity by turning wind turbines that can supply power and it can even be stored in the power grid.

Burgos Wind Farm in Ilocos Norte

The largest wind power project in Southeast Asia

Hydropower

Flowing water creates energy that can be captured and turned into electricity which is called Hydroelectric power. Water is constantly renewed by the water cycle. The mechanical energy from flowing

Geothermal Energy

The earth is constantly being warmed up by its core so when we use ____, we don't use up resources like we do when we burn gas. Comes from the heat generated deep within the Earth's core, usually found at tectonic plate boundaries near volcanic activity.

Biomass

refers to organic material from plants or animals including wood, sewage, and ethanol

Non-Renewable Resources

are exhaustible natural resources such as mineral resources that cannot be regenerated or replenished after exploitation (OECD, 2001b)

Fossil fuels

were formed within the Earth from decomposing plants and other organisms, buried beneath layers of sediment and rock, over millions of years to become carbon-rich deposits

Minerals

are naturally occurring inorganic substances found under varying conditions and in different types of geological environments. They have a crystalline structure and come with a definite chemical composition. Minerals are divided into two types, namely: metallic and nonmetallic minerals.

Nuclear energy

is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission - when nuclei of atoms split into several parts -or fusion - when nuclei fuse together.
