Can Light help people improve their
lives or decrease?
By: Wesley Piera
My First Question is, ‘Can Light help people improve
their lives?’. I wanted something that affected our
world majorly. 80% of Humanity lives on less then
10$ a day. Can light help them?
Second Question: ‘Does using light increase our
pollution around the world?’ I found this question by
researching my first question and found some
What is Light?
There are many kinds of light and many ways to
use it. Mostly Light is used to generate power,
grow plants and see. Light is generated by
mostly 2 ways, from Electricity and from the
Sun. Light lets us see, without we would be
going about the world dark and hopeless.
Light and Pollution?
Sunlight is free, we don’t pay for sunlight. When we gather electricity
from other resources such as coal, it causes major pollution. When
using Hydro, only cities by lakes or rivers can use it. Cities in Africa
are covered in desert and when trying to make Hydro Electricity you
have to make a dam but they need water, they don’t want to waste
it generating electricty. Wind is good but it isn’t reliable. Winds
could come any day of any hour of any place. When you build a
turbine you would need to build it in a certain spot to get the most
wind. If you put it in a place with no wind, it wouldn’t be generating
electricity and it would be a waste of money and resources. When
generating light from other resources, they cause pollution. Such as
coal realising chemicals in the air. Clouds, pollution and wind can
prevent the sun's rays from reaching the earth.
Solar Panels Facts
Solar Energy is better for the environment than
traditional forms of energy.
Solar energy can also be used to heat swimming
pools, power cars, for attic fans, calculators and
other small appliances. It produces lighting for
indoors or outdoors. You can even cook food with
Solar Energy is becoming more and more popular.
The worldwide demand for Solar Energy is
currently greater than supply.
All this is powered by Light, which is free.
Coal Generation Facts
Coal is the number one source of total US electricity
production (54%).Out of the entire US electric industry, coal-fired
power plants contribute 96% of sulfur dioxide emissions (SO2),
93% of nitrogen oxide emissions (NOx), 88% of carbon dioxide
emissions (CO2) and 99% of mercury emissions. Coal-fired power
plants are the single largest source of mercury pollution in the US
A single 100 megawatt (MW) coal-fired power plant emits
approximately 25 pounds of mercury a year
50% of the mercury emitted from coal-fired power plants can
travel up to 600 miles from the power plant
Hydro Power Facts
Hydropower today provides about 20 % of the
world's electricity and is the main energy
source for more than 30 countries
When building dams, it can affect the wildlife
such as fish, and can affect the river
ecosystem all together.
Hydropower is the most significant renewable
Hydro Power doesn’t produce pollution
Is light Good for us?
That’s like asking do we need food? Of course Light
is good for us. Everyday, the sun pours
unimaginable amounts of energy into space.
Some of it is in the form of infrared and
ultraviolet light, but most of it is in the form of
visible light. Some of this energy falls on the
Earth, where it warms our planet's surface, drives
our ocean currents, rivers, and winds, and is used
by plants to make food. Life on Earth depends
totally on the sun. Without the light, we would
die by no food because sun produces food or
freeze to death. Light is important and needed to
our world or else face extinction
You don’t have to watch the full thing just skip through it
• There is a type of generating electricity call Nuclear
Generation. When you hear the words "nuclear power,"
different images may flicker through your mind: concrete
coolant towers emitting torrents of steam, a mushroom
cloud rising high into the sky or even homer Simpson
asleep at the control
Some people praise the technology as a low-cost, low-
emission alternative to fossil fuels, while others stress the
negative impact of nuclear waste and accidents such as
Three Mile Island and Chernobyl. People don’t use this as
much because it is very dangerous and highly explosive.
Nuclear as in Nuclear Bomb can be very explosive if blown
up, this is why not everyone uses this but some do like in
Ottawa they use Nuclear Power Plants.
LUTW – Light up the World
What is it? Light up the World is the first
international humanitarian organization
dedicated to illuminating the lives of the
world's poor by providing affordable, safe,
healthy, efficient, and environmentally
responsible lighting. There are many great
organizations aimed at providing assistance
for people without electricity. They so far have
lit up 14, 000 homes in 42 different countries.
Pretty AMAZING EH?!?!?!?
What LUTW did
The existing method for lighting homes with no
electricity in poorer countries is most commonly
kerosene lamps. Although they are effective,
kerosene lamps have a lot of issues. They are
dangerous, unhealthy, pollution producing, and
require on ongoing supply of kerosene gas which
is expensive and not always easily accessible.
Light Up The World’s solution is to provide basic
LED lamps to replace the kerosene ones. LEDs
provide very bright light with minimal energy
input, so little in fact that they can be easily
charged using small solar panels.
How this affected the people
There are parts of the world that have little or
no access to electricity. When LUTW helped
them, They access to heat and light (even
after the sun goes down), convenient ways or
storing and cooking food, communication with
the outside world, and much more.
Why I picked LUTW
There are many great organizations aimed at
providing assistance for people without
electricity. They all help countries that are in
need of support or money, but one group
stood out before all of them which was LUTW.
I got more research by this because my moms
friend was in this group and provided me with
research and how the group worked.
My conclusion is that yes Light does help
improve their lives by many different ways.
Such as communicating, cooking and many
more things during the light. Also allowing
them to see. And no, using Light does not
produce more pollution around the world. All
it needs is sunshine and that’s free.
