#renewable #non-renewable #resources #ngscience
All about the Earth’s resources and how their use by people can impact the environment.

The Earth is full of natural resources. A natural resource is a part of the Earth that people use. It includes things like sunlight, wind, water, plants and animals and fossil fuels like coal, oil and natural gas.

Some natural resources are renewable. This means they are replaced or replenished by nature when they are used…so they wont run out. They can be used now and by future generations too. Sunlight, wind and water are examples of renewable natural resources.

Some of the natural resources people use are non-renewable. A non-renewable natural resource is a resource that is not able to be replenished by nature at the rate in which they are being used. Fossil fuels, like coal, oil and gas are non-renewable. Fossil fuels are formed when organic matter deep beneath the Earth’s surface are subject to heat and pressure over millions of years. The fuels can be burned to produce heat which is used by people in a number of ways. They are used in combustion engines to power cars, buses and other vehicles. They are also used to produce electricity.

Coal is a fossil fuel that is found beneath the surface of the Earth. To get coal, a mine needs to be constructed. This can cause large and widescale changes to the environment. Trees and plants are removed to make way for the mine and the network of roads needed to transport people and coal out of the area. A major impact of coal mining is habitat loss. This occurs when human changes to the environment result in there being insufficient resources for organisms to survive. Some animals may move to a new suitable habitat. Most organisms however, will die.

To get natural gas and petroleum, people must drill deep into the Earth’s surface. Sometimes chemicals are used to pump the fuels from the Earth. These chemicals can pollute the land. Land and water pollution can also occur when these fossil fuels spill into the natural environment.

The burning of fossil fuels has another impact on the Earth – air pollution. The emissions released into the air when fossil fuels are burned are harmful to organisms, including people. The emissions also include greenhouse gases that trap solar radiation in the atmosphere and increase the rate at which the Earth is warming – a process called human-induced climate change. Scientists have discovered solid evidence that the burning of fossil fuels by people is causing the Earth to get warmer at a much faster rate than it normally would. This is caused the water level in our oceans to rise, the melting of the Earth’s polar ice caps and causing changes to many of Earth’s habitat making them unsuitable for the organisms that depend on them.

Is offshore wind the energy of the future?

Alternative Energy No Comments »

Offshore wind farms solve one of renewable energy’s biggest problems: unreliability. With wind almost always blowing on sea, there is no lack of power. But the technology is struggling with a bunch of other hurdles.

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.

Wind Energy | Future of Renewable Energy | Full Documentary

Alternative Energy No Comments »

Wind power is one of the fastest-growing renewable energy technologies. Usage is on the rise worldwide, in part because costs are falling. Global installed wind-generation capacity onshore and offshore has increased by a factor of almost 75 in the past two decades, jumping from 7.5 gigawatts (GW) in 1997 to some 564 GW by 2018, according to IRENA’s latest data. Production of wind electricity doubled between 2009 and 2013, and in 2016 wind energy accounted for 16% of the electricity generated by renewables. Many parts of the world have strong wind speeds, but the best locations for generating wind power are sometimes remote ones. Offshore wind power offers tremendous potential.

Wind turbines first emerged more than a century ago. Following the invention of the electric generator in the 1830s, engineers started attempting to harness wind energy to produce electricity. Wind power generation took place in the United Kingdom and the United States in 1887 and 1888, but modern wind power is considered to have been first developed in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-metre wind turbine began operation in 1897.

Wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems. Wind first hits a turbine’s blades, causing them to rotate and turn the turbine connected to them. That changes the kinetic energy to rotational energy, by moving a shaft which is connected to a generator, and thereby producing electrical energy through electromagnetism.

The amount of power that can be harvested from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and to the cube of the wind speed. Theoretically, when wind speed doubles, wind power potential increases by a factor of eight.

Wind-turbine capacity has increased over time. In 1985, typical turbines had a rated capacity of 0.05 megawatts (MW) and a rotor diameter of 15 metres. Today’s new wind power projects have turbine capacities of about 2 MW onshore and 3–5 MW offshore.

Commercially available wind turbines have reached 8 MW capacity, with rotor diameters of up to 164 metres. The average capacity of wind turbines increased from 1.6 MW in 2009 to 2 MW in 2014.

In this video, we are going to look at Solar Photovoltaic Thermal Hybrid collector or in short PVT. Its a combination of solar thermal collectors and PV cell.
The removal of heat from PV cells is also improved and the overall output increases to 85%. The added output is in the form of heat.

Given that over 50% of the energy we consume is in the form of heat, this is a valuable device.

What Is The Future Of Hydropower?

Renewable Energy No Comments »

Hydropower is the world’s largest source of renewable energy, yet we don’t hear much about it. That’s in part because hydropower generation in the U.S. has remained relatively steady for decades. But internationally, it’s been growing rapidly, especially in China. That growth has some environmentalists concerned, as dams and reservoirs disrupt the surrounding ecosystems and can create C02 and methane emissions. Plus, hydropower generation is threatened as climate-driven droughts become increasingly common. Yet many experts say that hydropower is absolutely vital for a fossil fuel-free world and so learning how to mitigate these challenges will be critical in the decades to come.

The Future of Energy – Episode 2: Offshore Wind Power

*****************************************************************************

The global annual potential of onshore and offshore wind power is around 840,000 TWh, that’s almost 40 times that world’s annual power consumption!

The Global Wind Power capacity has more than doubled since 2012 from around 280 GW to over 650 GW today.

650 GW power capacity generates enough electricity to power the US and India combined.

Along with the growth in capacity, the wind turbines themselves have grown over the years.

The diameter of commercial turbine rotors was around 17m in the 1980s and generated around .07 MW.

Today, the average rotor is over 116m and generates over 2.4 MW.

The giant turbines used today are made possible by the advancement of material science, allowing the giant blades and shafts to withstand a tremendous amount of stress.

These larger turbines have led to a substantial drop in cost over the past 40 years.

The cost of wind power was 38 cents per kWh in 1980: today, it’s less than two cents!

Alright, so how do these incredible devices work?

Wind turbine are like plane propellers but in reverse.

Instead of an engine powering propellers to generate a wind force, the wind blows through the rotors and powers the engine.

This boils down to the Bernoulli Principal.

The shape of the blade causes air to take a longer path around one side compared to the other.

And this creates a difference in air pressure causing the blade to pull toward the low-pressure side, which spins the rotor.

Inside the turbine housing lies coils of wire that spin inside a magnetic field generating an electric current.

The downside to wind power is that only certain parts of the world have consistent wind at the ideal speed, which is between 21 and 26 km/h.

This map highlights the area that contains ideal wind speeds.

The areas in yellow, orange, and red are great places of wind turbines.

However, the map does not cover the shorelines, where the winds are much more constant than on land.

Offshore wind power is the fastest-growing sector in wind power lead by the UK and Germany.

The UK has three of the largest offshore wind farms in the world, the largest at the moment being the Hornsea Farm.

Hornsea has a massive 1.2GW capacity and is located 120 kilometers off England’s Yorkshire coast and will produce enough energy to power 1 million homes.

The farm has 174 turbines, each standing 100 meters tall.

Each Turbine can power the average home for an entire day with just a single rotation.

And if you think that’s impressive, General Electric has developed a wind turbine that makes the ones on the Hornsea farm look like children.

Enter the Haliade-X wind turbine.

The Haliade-X is gargantuan, standing 260 meters tall, equipped with 107 long blades.

With a 12MW capacity, a single Haliade turbine can power 16,000 homes.

GE recently constructed a prototype Haliade in the Netherlands; this is a time-lapse of the construction.

GE plans to commercialize Haliade by 2021 and will supply up to 300 of the massive turbines to the Dogger Bank wind farm.

Dogger Bank Wind Farm will be the largest offshore wind farm in the world with a massive 3.6 GW capacity and will power 4.5 million homes in the UK.

Constructing offshore turbines require specialized vessels called offshore Jack-up Installation Vessels.

And the installation of Haliade-X turbines will require the largest jack-up vessel in the world, the Voltaire, being constructed by Jan De Nul Group.

The Voltaire is a behemoth at almost 170 meters long.

Voltaire’s lifting capacity of 3,000 tons is twice the capacity as Jan De Nul’s next largest vessel.

Anyway, the UK is gearing up to be carbon neutral by 2050, and with the help of these incredible offshore wind farms, it is well on its way.

Scotland generated twice the power it needs from wind power in the first half of 2019.

And offshore wind power is going to expand well beyond the UK in the coming years.

Germany is not too far behind the UK.

The country has almost 1500 offshore wind turbines with a capacity of 7.5 GW and is expecting to grow to 15 GW by 2030.

The Global Wind Energy Council projects the global offshore wind market to grow from 20 GW today to 190 GW by 2030.

And the total investment in offshore farms could reach trillion by 2040.

So, wind offers a vast amount of renewable energy that is readily available, no mining, drilling, or fusing of atomic nuclei required.
