AI Is Hungry for Power – And How We’re Feeding It

AI isn’t just smart. It’s hungry. And what it craves most is power. Not the world-domination kind, but real electricity. Just training one large AI model can use as much energy as 100 American homes use in a year. That’s just the training part. After that, AI models run in huge data centers—buildings packed with servers that never sleep.

By 2027, AI could use up to 3.5% of the world’s electricity, according to experts. That’s more than many countries use. And where does that energy come from? Mostly fossil fuels. So every AI chatbot or image generator might be quietly warming up the planet.

Scared yet? You should be. If we keep feeding AI like this, we’re looking at more pollution, more power outages, and a world where machines are draining our planet faster than we can fix it.

But we’re not helpless. We can steer things the right way.

Here are 5 smart ways to stop an AI power crisis:

Build greener data centers – Use solar and wind to power AI, not coal.

Smaller models, smarter use – Don’t use giant AI for every small task.

Stronger rules – Governments must set limits on how much power AI can use.

Teach people – Everyone should know how AI works and what it costs.

Use staff augmentation companies – They let you hire AI experts without wasting resources. Partnering with a staff augmentation company [/https://epicx.co.uk/] is cost-savvy, efficient, and keeps AI in human hands.

AI is a tool. Let’s treat it like one—not like a god. Want to explore how smart hiring can help keep AI in check? Try staff augmentation, green tech options, or AI energy stats.

how to have a sustainable city

To have A sustainable city such as Copenhagen Denmark which city has 55% wind-powered city. This is a big contributor to how sustainable they are. Even with wind power they still use coal which is 17% of the energy they use. Copenhagen has some of the best biking opportunities in the world with 45% of people commuting by bike. One of the corporate goals is to be 100% renewable energy by 2050. What are some ways you can reduce the carbon emissions in your city ( info from https://carbonneutralcities.org/cities/copenhagen/)

AuleBOD   2025-05-28 21:39:21 in Sustainable City

Some ways that people can reduce emission in their cities is by using public transportation as the cities in Europe have been shown to use. I personally use my cities public transportation called BART, which is a train that takes me from my house to San Ramon every weekend. If I were to take a car every weekend instead of BART then the emissions that just I would emit would be far greater then if I continued using the train. If everyone in my city used as much public transportation then the emissions would decrease a lot.

How transportation plays a huge role in carbon emissions?

Transportation plays a big role in carbon emissions because most vehicles that aren't electric run on fossil fuels like gasoline. This causes tons C02 to be released into the atmosphere when cars, trucks and airplanes burn these fuels. In many countries transportation in the biggest source of C02. To help the planet we need transition from using gas transportation to using electric cars, biking places more, or using more public transportation, also cities making public transportation electric can also help a lot.

how meat affects your carbon footprint

something that everyone can do to reduce there carbon footprint is eating less meat. Even though i do realize meat is a crucial part of a lot of people’s diets and not an easy thing to give up, i still think a lot of people aren’t aware of the serious affects meat has on our environment. The 1st thing i have to say about meat is how much land it takes to raise meat that is fully grown, one thing i’m not sure most of you know is that feeding someone who is vegan for a year takes only 1/6th of an acre of land while someone on a meat and dairy diet for a year uses 18 times that amount of land. i think this is a very scary statistic but also a very real one, raising meat does use a lot of land and meat eaters have to realize that. the 2nd thing i have to say about meat is how much methane cows produce. cows produce this methane through there farts, burps or poop, we contribute to this by eating cows. considering how many cows are bred because of the demand we put on them meaning more of the methane that cows produce is going up into the atmosphere. i think it is a really good idea for people to consider eating less meat and dairy meals each week as it is a great way to help save our planet and reduce your carbon footprint.

According to the Food and Agricultural Organization, over 900 million people on Earth don’t have enough food to eat. This is nearly 1 in 7 inhabitants on Earth. Assessing our carbon footprint in correlation with our dietary choices shows that plant-based diets, often vegan or vegetarian, substantially reduce greenhouse gas emissions as opposed to meat-heavy diets.

mija28   2025-05-23 10:36:09 in Food & Hunger

I agree with you, eating less meat is a great way to help the planet. Raising animals uses a lot of land. A vegan diet can cut land use by up to 75% (University of Oxford), which means more space for vegetation and animals. Also, cows release a gas called methane, which traps heat and harms the atmosphere. The EPA (Environmental Protection Agency) says methane is over 25 times stronger than carbon dioxide. Even eating a few plant based meals each week can lower your carbon footprint and help the Earth.

Carbon Footprint of the US

I was very surprised by the high carbon levels in America compared to other countries' averages. It got me thinking: why is America so bad at reducing its emissions? I have a couple of solutions to this, starting with producing more naturally produced foods or producing things like meat in a more carbon-efficient way. This could bring down the carbon footprint immensely if people in the US did not eat at fast food restaurants so much and supported more places that sell natural foods. We could also switch things like gas stoves and gas cars for electric stoves and electric cars, which emit less carbon than gas-powered items.

Supply/Demand

People always say not to buy fast fashion, but why? If the clothes are already there in the store what difference does it make if I buy them? You have probably also heard of supply and demand. When there is high demand for a product, more supply will be made. When you buy clothes, decor, etc. from fast fashion stores you are creating demand. Then, companies create more supply to meet this demand. If we keep up this mindset that what we buy doesn't matter, then companies will keep creating supply, and damaging the earth.

mazaBOD   2025-05-22 21:19:24 in Wants or Needs?

I agree, and I think a way to bring down the demand is for more people to switch to thrift shopping. It is much more environmentally sound, it saves money, and as an added bonus makes you swaggier. The more people who switch to this environmentally sound way to shop, the less demand the stores will recieve, and the less they will produce, ultimaely leading to much less waste from clothing items. Although thrifting is a great way to reduce personal global impact, I believe there also needs to be more laws and regulations in the clothing industry because fast fashion is thriving despite having a continuously bigger impact on the environment. There needs to be a limit on the amount of clothing items that can be produced at once, ensuring the least amount of excess stock.

Plastic, paper and metal straws

Do paper straws, that we get in almost every shop whit a drink, actually make a diffrance in the global carbon footprint? I am sceptical because we need to cut down a tree for them and after we use them, we cant reuse them like a plastic straw. Also they usualy come in a plastic pacaging so i dont see the point. At our homes there is a option to use metal straws but i dont like them because they are hard to clean and im not sure if they have better carbon footprint than plastic straws. Please tell me if you know a better alternative to plastic straws.

KaMeBOD19   2025-05-20 19:25:11 in Sustainable City

I know this doesn't seem helpful, but not using straw in general and sipping from a cup is probably the best solution that you'll ever find. One with zero waste and zero down side, unless you count something on your lip when you're drinking something a little more dense. Another solution though that I researched is pasta straws. I found a company named Pasta Life that makes straws made of pasta so you can just eat your straw right after which is also zero waste. The down fall was that you can't use it in hot beverages, but almost all hot beverages are better straight out of the cup anyway.

Carbon Footprint

I was very surprised to see how high my carbon footprint was, especially from the amount of traveling I did. I think, in my general area the carbon footprint was so high because most of the people in my neighborhood leave their lights on in their house before they leave for the day, which usually means they'll be gone for several hours of the day. I also do this sometimes but I should stop to reduce my carbon footprint, I think other people can also stop doing things like leaving the water running and using their cars to travel places that are close to reduce fossil fuel emissions.

Factory Farming and the Environment

Many of us are probably used to eating meat, dairy, eggs and other animal products quite frequently, if not every day. What a lot of us don't know (or choose to ignore) is the horrors that go on inside the meat/animal product industry. The animals in them are subjected to short, tortuous lives, with many living cramped together and in inhumane conditions. In addition to all of that, it is horrible to the environment, with factory farming being one of the leading cause of greenhouse gases worldwide.Eating less meat could help to reduce our carbon emissions as a group effort, and would help the environment and the animals as well.

The Carbon Cost of Flying

Air travel is one of the most carbon-intensive activities an individual can engage in. According to the International Air Transport Association (IATA), commercial aviation accounts for about 2–3% of global CO₂ emissions, but its overall climate impact is higher due to the release of other gases at high altitudes, which amplify warming effects (Lee et al., 2021). Air travel has become an integral part of global connectivity, enabling economic development, cultural exchange, and personal freedom. However, its environmental cost—particularly in terms of carbon emissions, is significant and often underestimated.

Would Climate Change occur without Human intervention?

Climate change is a very real and is mainly caused by humans, although many people are doubtful this is even occurring. Climate change is the long-term change in Earth’s temperature, weather patterns, and climate systems. According to NASA and the National Oceanic and Atmospheric Administration (NOAA), the Earth’s average temperature has increased by about 2 degrees Fahrenheit since the late 1800s, and most of that increase has happened since 1975. This is due to the pollution from cars, factories and power plants. However, there have been natural factors that contribute to climate change such as volcanic eruptions or changes in the sun’s energy. While these might not be the main causes, they do speed up the process. Without humans, climate change may occur over many years, but nowhere near as quick or devastating as it is now.

Wants or Needs

The strong want to be able to have the popular things/items that are seen all over the internet, muddle the opinion of whether it is actually needed, or do we want it so bad that it feels like we need it? Lots of things are bought because someone wants it, but when something is needed, people noticeably slack on buy that item because it isn't wanted.
