Clean Energy and Clean Vehicles
A lot has been discussed and written about
replacing much of our energy use with renewable sources like solar and wind,
and replacing our fossil fuel guzzling and polluting vehicles with battery
powered electric vehicles.
The starry-eyed among us propose building solar
panels, windmills, EV’s and charging stations across the land, plugging our
cars in, and “off we go”, paying little attention to the science, engineering
and practicality of the issue.
Here are some references that discuss energy
production, electric vehicles and such, both pros and cons.
A review of this material, which is both
starry-eyed optimistic on the one hand, and negative and derogatory on the
other, points out several issues.
Comments on Sources of Power
-
Solar and Wind
-
Relying on solar and wind as the main source of
power generation has been shown to be impractical with current technology and
conditions. Sun and wind are
unreliable. Also, solar panels are
primarily made in China by slave labor.
Wind turbines are massive, expensive and elicit environmental concerns. Sun and wind and tides make excellent
supplements to other main power sources, and could comprise as much as 20-25%
of a country’s power requirements in some locations. However, they are not likely as a country’s main
source of power.
-
-
Hydropower
-
The use of hydropower involves using the kinetic
motion in water as it flows downstream, part of the normal water cycle of the
Earth, to generate other forms of energy, most notably electricity. Dams use
this property as a means of generating electricity. This form of hydropower is
called hydroelectricity. All countries
take advantage of hydro generated power, with Brazil, Canada, China and France
as major users.
-
-
Geothermal
-
The Earth generates a lot of heat while going
about its normal business, in the form of subterranean steam and magma among
others. The geothermal energy generated within the Earth's crust can be
harnessed and transformed into other forms of energy, such as electricity. Kenya, Iceland, Philippines, El Salvador and
New Zealand produce as much as 30% of their electrical power from thermal
sources.
- -
Biomass
-
Biomass is not really a separate type of energy,
so much as a specific type of fuel. It is generated from organic waste
products, such as cornhusks, sewage, and grass clippings. This material
contains residual energy, which can be released by burning it in biomass power
plants. Since these waste products always exist, it is considered a renewable
resource. Major countries producing energy from biomass are Germany, U.S.,
China, Japan.
-
-
Nuclear (fission) power generation makes use of
the thermal energy produced when a uranium nucleus is split. This energy is
used to produce high-temperature, high-pressure steam from water boiled inside
the nuclear reactor. The steam then drives a turbine for generating
electricity. While nuclear processing
and nuclear power plants produce radioactive wastes and the potentially for
environmental disaster could be large, the advantages of nuclear power in
generating large amounts of sustainable energy without polluting the atmosphere
with toxic fumes and greenhouse gases outweighs the disadvantages of nuclear
power. Accidents at Three Mile Island,
Chernobyl and Fukushima have poisoned public opinion about producing power
using nuclear plants. Many countries
have nuclear reactors producing power. France
has adopted nuclear in a big way, while Germany has phased it out completely.
-
-
Fusion power is a proposed form of power
generation that would generate electricity by using heat from nuclear fusion
reactions. In a fusion process, two lighter atomic nuclei combine to form a
heavier nucleus, while releasing energy. Devices designed to harness this
energy are known as fusion reactors. Research into fusion reactors began in the
1940s, but to date, no design has produced more fusion power output than the
electrical power input.

Batteries
– Materials
-
The
materials in electric car batteries include elements such as lithium, cobalt,
manganese, nickel, graphite, and other metals and materials. These raw
materials are processed and individual battery cells are made. There is a
cooling system and electrical power management system added to regulate the
battery.
-
-
One
of the biggest suppliers of raw cobalt is the Democratic Republic of Congo with
around 60% of the world’s cobalt coming from here.
-
-
China
dominates the Lithium-ion battery production as they produce about 65% of the world’s
lithium-ion batteries as of February 2021.
-
-
A
sodium-ion battery is being produced and many are very hopeful that it could
replace the lithium-ion battery in electric cars. Sodium-ion batteries are not the only new
type of batteries that are currently being researched, but if a few different
types of batteries can be produced that have similar results, powered in a
similar way, and even recycled, then we may have a chance to never run out. If
this is the case and we can properly spread out the use of these materials, we
could have plenty of materials for years to come and in a perfect world maybe
even never run out.
-
-
Right
now, these batteries are not being recycled to their full potential and more
research is being done to make the recycling of these batteries more viable but
as of now this process is not refined and could cause some alarm if not handled
correctly in the near future.
