how to make electricity from water / hydro power generator homemade
about the video
hydro power, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy. In the early 21st century, hydroelectric power was the most widely utilized form of renewable energy; in 2019 it accounted for more than 18 percent of the world’s total power generation capacity.

As the U.S. attempts to shift away from fossil fuels, renewable energy resources bring waste problems of their own. Recycling or disposing of wind turbine blades and solar panels can be tricky, and many often just end up in land fills. Ben Tracy reports.

Want to learn more about the topic in this week’s video? Here are some key words/phrases to get your googling started:
– Radiation balance – incoming radiant energy from the sun minus outgoing energy heading into space.
– Infrared radiation – electromagnetic radiation that is invisible to us; comes in longer wavelengths than visible light and provides energy transfer we call heat.

Sanford School of Policy professor Billy Pizer outlines the challenges of designing policies that rein in the environmental impacts of energy use.
While it’s true that Earth’s temperatures and carbon dioxide levels have always fluctuated, the reality is that humans’ greenhouse emissions since the industrial revolution have put us in uncharted territory.

The global food system is responsible for between 20-30% of greenhouse gas emissions, most of which are generated at the production stage. Take rice, for example, a food staple that is eaten regularly by over half the world’s population.
Conventional rice production generates emissions equivalent to the entire global aviation industry. So how can we produce rice in a way that uses fewer resources and regenerates nature? A growing number of farmers around the world are changing the way they produce rice, by adopting an agroecological approach called the System of Rice Intensification (SRI).
This method relies on a small group of simple interventions that together significantly reduces water use, methane production, and the use of chemicals, while providing better yields and reducing labour for rice farmers.
Multinational companies who support this type of agriculture through procurement and product design can address their scope 3 emissions and build resilience in their supplier communities.
According to Project Drawdown, SRI currently accounts for 4% of rice production. If this was increased to 25%, the emissions reduction would be equivalent to that which is currently generated by the whole of India.

Clean energy from re-growing resources and waste. Biomass sounds like a perfect alternative power source. Globally, at least 5% of energy come from biomass. But what does it mean if we use organic matter for fuel or electricity?
We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.

“Wood is one of the few energy sources that emits more carbon than coal.” Burning biomass allowed civilization to evolve and advance in remarkable ways, but smoke that comes as a byproduct is carbon-heavy and kills around 2 million people per year.
