energy

2. Wind Turbines
• A wind turbine is a popular name for a
device that converts kinetic energy from
the wind into electrical power.
Technically there is no turbine used in
the design but the term appears to have
migrated from parallel hydroelectric
technology.

4. Solar Panels
• Solar panel refers either to a photovoltaics
module, a solar hot water panel, or to a set of
solar photovoltaics modules electrically
connected and mounted on a supporting
structure. A PV module is a packaged,
connected assembly of solar cells. Solar
panels can be used as a component of a
larger photovoltaic system to generate and
supply electricity in commercial and
residential applications.

6. Hydropower
• Hydropower or water power is power derived from
the energy of falling water or running water, which
may be harnessed for useful purposes. Since ancient
times, hydropower from many kinds of watermills has
been used as arenewable energy source
for irrigation and the operation of various mechanical
devices, such as gristmills, sawmills, textile mills,trip
hammers, dock cranes, domestic lifts, and ore mills.
A trompe, which produces compressed air from
falling water, is sometimes used to power other
machinery at a distance.

8. Biomass
• Biomass is biological material derived
from living, or recently living organisms.
It most often refers to plants or plant-
based materials which are specifically
called lignocellulosic biomass. As an
energy source, biomass can either be
used directly via combustion to produce
heat, or indirectly after converting it to
various forms of biofuel.

10. Electronic Vehicles
• An electric car is an automobile that
is propelled by one or more electric
motors, using electrical energy stored
in rechargeable batteries or
another energy storage device. Electric
motors give electric cars instant torque,
creating strong and smooth
acceleration.
