Renewable energy: (Renewable energy is generated from
sources that naturally replenish themselves and never run out)
The most common renewable energy sources are solar, wind,
hydro geothermal and biomass
Hydro geothermal (Hydroelectric (is a form of energy generated
by the motion of water (kinetic energy) and is converted into
electricity) and geothermal (is heat stored deep inside the earth
or occasionally in hot springs)).

• Biomass: sinh khối (Biomass energy is energy generated
or produced by living or once- living organisms. (gt bằng
tiếng Việt: là nguồn năng lượng từ sự sống, hay gần đây
là sinh vật sống, đa số là các cây trồng hay vật liệu có
nguồn gốc từ thực vật)
• Fossil fuel(s): ( fossil fuels are made from decomposing
plants and animals. These fuels are found in the Earth’s
crust and contain carbon and hydrogen, which can be
burned for energy. For example: coal, oil, and natural
gas) ( năng lượng hóa thạch)

Greenhouse: a building with roof and sides made of
glass, used for growing plants that need warmth and
protection. ( nhà kính)
Greenhouse gas emission(s): khí thải nhà kính
Ecological destruction: phá hủy hệ sinh thái
Intermittent (adj) liên tiếp ngừng rồi lại ngắt quãng
Nuclear power: năng lượng nguyên tử.

5. Nuclear waste storage includes:
+ Onsite storage: lưu trữ tại chỗ
+ Long term deep storage: lưu trữ lâu dài
+ Reprocessing fuel for use in other nuclear energy
plants: lưu trữ cho các nhà máy năng lượng hạt nhân khác.

Around the world, renewable energy use is on the rise and these alternative energy sources could hold the key to
combating climate change. What is renewable energy? Renewable energy is generated from sources that naturally
replenish themselves and never run out, the most common sources are solar, wind, hydro geothermal and biomass. Over
80% of the total energy consumed by human is derived from fossil fuels however renewable are the fastest growing
source of energy in the world. Renewable energy has many benefits: first, it can combat climate change because the its
creates no direct greenhouse gas emissions. The only emissions that they produce are indirect meaning those that result
from manufacturing parts installation operation and maintenance but even those are minimal; second, renewable energy
can decrease pollution and therefore reduce threats to our health. Wind, solar and hydroelectric systems create no air
pollution emissions and geothermal and biomass energy systems emissions are much lower than non-renewable energy
sources; third, renewable energy is a reliable source of power because renewable energy source are well renewable they
will never run out. Once built renewable facilities cost fairly little to operate and the fuel is often free, as a result
renewable prices tend to be stable over time while renewable energy has many advantages it is not without downsides. It
is difficult for renewable energy sources to generate power on the same large scale as fossils fuels. Building wind farm and
dams can disrupt the wildlife and migration patterns and lead to ecological destruction. Both solar and wind energy are
intermittent they only generate power while the sun is shining or while the wind is blowing, batteries can store excess
energy for later use. However, they are often costly while renewable energy some challenges, it also offers an
environmentally friendly alternative to the greenhouse gas emissions and pollution of fossil fuels and as advances in
technology make renewable energy more accessible affordable and efficient an end to climate change could be within our
reach.

What role does nuclear power play in a full transition away from fossil fuels and towards a zero-carbon future? As i came to
realize while researching this video, the debate behind nuclear power is complicated, and in order to really analyze the value
of nuclear power as an energy source, it is important to look at emissions, waste, cost, and safety. Let’s start with emissions,
which are a huge factor when trying to understand whether nuclear power is a serious option for mitigating clamte change.
Many proponents of nuclear point to the lack of greenhouse gas emissions from power plants as a major reason to increase
nuclear energy production. While this is true for actual nuclear fission process that creates energy, the processes surrounding
nuclear, like uranium mining and refining demand emissions. A life cycle assessment of various fuels conducted by the IPCC
reveals that the average greenhouse gas emissions of nuclear power production is relatively the same as renewable
counterparts. But, when compared to natural gas and coal, nuclear emission are drastically lower. So as an alternative to
gas and coal, nuclear power is certainly less emissions heavy, and could be a viable low- carbon energy option. But waste
also comes hand in hand with emissions. This is big sticking point for the anti- nuclear movement, and rightfully so. No one
really implemented a viable long term solution for nuclear waste storage. There are currently three main options right now:
onsite storage, long term deep storage, or reprocessing fuel for use in other nuclear energy plants. Reprocessing spent fuel
sounds like a perfect solution, but it’s not. According to the Union of Concerned Scientists, one consequence of reprocessing
spent fuel could be the proliferation of nuclear weapons. The by-product of this recycling process is more plutonium, which
can be easily used to build weapons. In addition, only a little bit os the reprocessed waste can be used again, and you’re still
left with a host of other radioactive materials. And on top of all that, recycling this waste has a substantial cost tied to it. So,
ultimately, the only answer right now to our current nuclear waste is long-term storage. Unfortunately, the only country that is
currently setting up a facility is Finland. The rest just stockpile their waste onsite, with no options or ourlooks for long term
storage. The other two main elements that really hold back nuclear are cost and safety. Combined, the drawbacks of these
make nuclear an infeasible solution to a swift decarbonization of our global electrical grid. “ The cost of nuclear power is
extremely prohibitive and it’s very

Benefits of nuclear power:
+ Nuclear power is an alternative to gas and coal,
nuclear power is certainly less emissions heavy, and
could be a viable low- carbon energy option. (giải pháp

Drawbacks:
+ No one really implemented a viable long term solution for nuclear waste
storage. There are currently three main options right now: onsite storage, long
term deep storage, or reprocessing fuel for use in other nuclear energy plants.
(Không ai thực sự thực hiện một giải pháp lâu dài khả thi để lưu trữ chất thải
hạt nhân. Hiện tại có ba lựa chọn chính: lưu trữ tại chỗ, lưu trữ sâu lâu dài hoặc
tái chế nhiên liệu để sử dụng cho các nhà máy năng lượng hạt nhân khác)
+ The by-product of this recycling process is more plutonium, which can be
easily used to build weapons.
+ In addition, only a little bit os the reprocessed waste can be used again, and
you’re still left with a host of other radioactive materials. And on top of all that,
recycling this waste has a substantial cost tied to it.
(Sản phẩm phụ của quá trình tái chế này là nhiều plutonium hơn, có thể dễ
dàng sử dụng để chế tạo vũ khí. Ngoài ra, chỉ một chút thôi là chất thải đã qua
xử lý lại có thể được sử dụng lại và bạn vẫn còn sót lại một loạt các vật liệu
phóng xạ khác. Và trên hết, việc tái chế chất thải này có một chi phí đáng kể
gắn liền với nó.)
