Sustainable Energy

Renewable energy will be discussed, along with their examples in the Philippines, moreover, concerns regarding and the factors affecting energy management of a country will also be tackled

Sustainable Energy Management

conversion of sunlight into usable energy forms. Solar photovoltaics (PV) and solar thermal electricity are well established.

Solar Energy

Sun radiation arrives outside the Earth with a specific spectral distribution, which is modified throughout the atmosphere until reaching the Earth’s surface

Solar Radiation

The amount of solar energy available on a given location of the earth differs depending on the geographic latitude, time of day, and year

Solar Energy Availability

radiation from the sun that reaches the Earth without scattering and as it is the only one with a known vector (solar vector), it can be concentrated using technological devices

Direct Radiation

radiation that is scattered by the atmosphere and clouds

Diffuse Radiation

directly converts solar energy to electricity

Solar Photovoltaics (PV)

harnessing solar energy for thermal applications – domestics, industries, hotels, hospitals, leisure, etc

Solar Thermal

converts solar radiation into useful heat and its performance depends both on optical and thermal features

Solar Thermal Collector

troughs concentrate sunlight onto a receiver tube that is positioned along the focal line of the trough

Parabolic Trough Solar Thermal System

system takes advantage of numerous heliostats to reflect sunlight onto the surface of the high

Central Tower Solar Thermal System

one

Linear Fresnel Solar Thermal System

heliostats with sunlight focused on the engine with a cavity receiver on the focal point and one of the most efficient solar electric technologies

Parabolic Dish Solar Thermal System

mostly used in heating water for showers and used in heating water in swimming pools and showers

Flat Plate Solar Collectors

two

Heliostats

module manufacturing is being done in large plants, which allows for economies of scale, and it can be deployed in very small quantities at a time

Solar Photovoltaics Advantage

as PV generates power from sunlight, power output is limited to times when the sun is shining

Solar Photovoltaics Disadvantage

burning of wood, bark, branches, starchy roots, manure and other plant and animal materials to produce energy

Biomass Energy

heat generated by burning biomass in a boiler is used to produce steam which is used by a steam turbine which drives a generator to produce electricity

Biomass Energy Conversion

falling water produces energy which is harnessed as a valuable contribution to total energy supply

Hydropower

dams can have unwanted social and environmental effects such as drought, endangering freshwater biodiversity, and displacement of communities

Hydropower Impact

comes from capturing kinetic energy using turbines to generate electricity and can be onshore or offshore

Wind Energy

energy is the main driver of every nation’s economy and what one chooses as their sources has global environmental and financial effects

Sustainable Energy

refers to how final energy consumption in a given geographical region breaks down by primary energy source

Energy Mix

hydropower, geothermal, biomass, solar, wind, ocean, and biofuels

Renewable Energy in the Philippines

help determine environmental burdens from cradle to grave

Life Cycle of Energy Systems

fuel combustion during operations of coal-fired power plant emits vast majority of greenhouse gases

Coal Energy Impact

renewable energy systems are not without environmental effects

Renewable Energy Disadvantages

having a “build absolutely nothing anywhere near anything” mindset can only hamper a nation’s growth and can also hinder one’s goal in achieving 100% renewable energy

BANANA Mindset
