3. Solar energy
• Solar energy is radiant light and heat from the
Sun that is harnessed using a range of ever-
evolving technologies such as solar heating,
photovoltaic's, solar thermal energy, solar
architecture, molten salt power plants and
artificial photosynthesis

4. solar heating
• A solar thermal
collector collects heat by abs
orbing sunlight. The term
"solar collector" commonly
refers to a device for solar
hot water heating, but may
refer to large power
generating installations such
as solar parabolic
troughs and solar towers or
non water heating devices
such as solar air heater

5. Photovoltaic's
• Photovoltaics (PV) is
the conversion of light
into electricity
using semiconducting
materials that exhibit
the photovoltaic effect,
• The photovoltaic
effect is the generation of
voltage and electric
current in a material
upon exposure to light

6. Solar thermal energy
• Solar thermal
energy (STE) is a form of
energy and
a technology for
harnessing solar energy to
generate thermal
energy or electrical
energy for use in industry,
and in the residential and
commercial sectors.

7. solar architecture
• Solar architecture is an
architectural approach that
takes in account the Sun to
harness clean and
renewable solar power.
• It is related to the fields
of optics, thermics, electroni
cs and materials science.
• Both active and passive sola
r housing skills are involved
in solar architecture.

8. Molten salt power plants
• Molten salt technology is increasing the
efficiency and storage capacity of solar power
plants while reducing solar thermal energy costs.
• Molten salts are typically made up of 60%
sodium nitrate and 40% potassium nitrate, and
the salts melt at approximately 220°C.
• Molten salts are often used with concentrating
solar power (CSP) plants to store thermal energy
for electricity generation

10. Artificial photosynthesis
• Artificial photosynthesis is
a chemical
process that biomimics the
natural process
of photosynthesis to
convert sunlight, water,
and carbon
dioxide into carbohydrates a
nd oxygen. The term
artificial photosynthesis is
commonly used to refer to
any scheme for capturing
and storing the energy from
sunlight in the chemical
bonds of a fuel (a solar fuel)

11. Wind energy
• Wind energy is a form of solar energy.
• Wind energy (or wind power) describes the
process by which wind is used to generate
electricity.
• Wind turbines convert the kinetic energy in the
wind into mechanical power.
• A generator can convert mechanical power into
electricity.
• Mechanical power can also be utilized directly for
specific tasks such as pumping water.
