ABE 134 - What is renewable energy

what are the fossil fuels

- Oil - Coal - Natural gas

what are the renewable energy?

- Solar Energy - GEOTHERMAL ENERGY - HYDROPOWER - WIND ENERGY - OCEAN ENERGY -BIOENERGY

types of biomass for energy

- crops and agriculture residues - vegetable oil and animal fats - trash/garbage - sewage - animal manure - wood

Largest Solar Farm in the World:

Bhadla Solar Park, India

is produced from a variety of organic materials, called biomass, such as wood, charcoal, dung and other manures for heat and power production, and agricultural crops for liquid biofuels.

Bioenergy

systems use either the warm surface water or boil the seawater to turn a turbine, which activates a generator.

Electricity conversion

T or F. Without natural greenhouse effect, heat emitted by the earth would simply pass outwards from the earth's surface into space and earth would have an average temperature of about 15⁰C.

F. -20°C

T or F. Human Activities causes decreases greenhouse gases in the atmosphere

F. increases

NON RENEWABLE ENERGY

FOSSIL FUELS

______________ utilizes the accessible thermal energy from the Earth's interior. Heat is extracted from geothermal reservoirs using wells or other means.

Geothermal energy

harnesses the energy of water moving from higher to lower elevations.

Hydropower

is our most mature and largest source of renewable power, producing about 10 percent of the nation's electricity (2001)

Hydropower

powers the Agus VI Hydroelectric Plant located in Lanao del Norte

MARIA CHRISTINA FALLS,

derives from technologies that use the kinetic and thermal energy of seawater waves or currents for instance to produce electricity or heat.

Ocean energy

generate electricity from wind blowing across the sea.

Offshore wind farms

is the power that's generated by wind turbines located on land driven by the natural movement of the air.

Onshore wind energy

uses energy sources that are continually replenished by nature

Renewable energy

the most abundant of all energy resources and can even be harnessed in cloudy weather.

Solar energy

The ocean can produce two types of energy:

THERMAL ENERGY and from the sun's heat, MECHANICAL ENERGY hydrothermal system from the tides and waves.

world's largest hydroelectric facility.

Three Gorges Dam

harnesses the kinetic energy of moving air by using large wind turbines located on land (onshore) or in seaor freshwater (offshore).

Wind energy

reservoirs that are sufficiently hot but that are improved with hydraulic stimulation are called ___________________.

enhanced geothermal systems

the conversion of biomass into gas, which is burned in a gas turbine — is another way to generate electricity.

gasification

absorb and reflect heat radiated by Earth, preventing it from escaping into space

greenhouse gases

Reservoirs that are naturally sufficiently hot and permeable are called _________________

hydrothermal reservoirs

Biomass can also be heated in the absence of oxygen to chemically convert it into a type of fuel oil, called _____________

pyrolysis oil

A ______________ is a device that converts the kinetic energy of wind into electrical energy.

wind turbine

A _____________ is a structure that converts wind power into rotational energy using vanes called sails or blades, specifically to mill grain
