Answer:

We get non-renewable energy from sources that will run out or will not be replenished in our life times or in many, lifetimes.

Most non-renewable energy sources are fossil fuels like : coal, petroleum, and natural gas. Carbon is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360-300 million years ago) is called the Carboniferous Period.

Explanation:

Fossil fuels ,coal, oil, and natural gas, do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.

We don't really like using renewable like solar , wind , water etc I think it's due to the fact that they make life easier, and i think to process renewable energy takes time and money but it causes less harm so , see countries like China, Russia, and Japan . They are mainstays on all three lists. It's also worth noting the countries that are highly dependent on nonrenewable energy sources even though they do not consume as much.

But there is a new development as countries have started leading the way in using renewable energy .Countries like

Iceland. Iceland generates the most clean electricity per person on earth, with almost 100% of its energy coming from renewable sources that make the most of its unique landscape. ...

Sweden.

Costa Rica.

Nicaragua.

United Kingdom.

Germany.

Uruguay.

Denmark.

and surprisingly China

They may be the world’s largest polluter, but China is also the world’s biggest investor in renewable energy, with huge investment levels both at home and overseas. China now owns: five of the world’s six largest solar-module manufacturing firms; the largest wind-turbine manufacturer; the world’s largest lithium ion manufacturer; and the world’s largest electricity utility.

Morocco

Morocco is a country with an abundance of sunshine (up to 350 days a year), so it has wisely decided to invest heavily in solar powered energy production. The first phase of the world’s biggest concentrated solar plant recently opened in Morocco and in combination with their wind and hydro production facilities, is predicted to produce enough energy for more than one million years

USA

The United States of America has one of the world’s largest installed solar PV capacities and an installed wind energy capacity second only to China. But it is also one of the world’s biggest energy consumers, which tends to cancel out much of its renewable capacity. Nevertheless, if more attention was paid to renewables over fossil fuels, it has been estimated that the U.S. could reduce its emissions by almost 80% in only 15 years, without impacting on consumer electricity costs.

Kenya

In the past, Kenya has been forced to import electricity from neighbouring countries, but they are working hard to reverse this by investing heavily in geothermal energy production, which accounted for more than half their energy mix in 2015. They also have Africa’s largest wind farm, providing another 20% of their installed electricity generating capacity.

I hope it helps plz mark me brainliest:)

Answer:

Because it makes our lives easier.

Explanation:

When we talk about nonrenewable resources, it's usually fossil fuels that derive from crude oil. After dividing the useless crude oil into different fractions, you get gases, petrol, kerosene, diesel, fuel oil and bitumen. Each fraction has their own unique purpose i.e: petrol as a fuel for cars.

We use plastic bags for our ease. They consist of a long chain of 'alkenes' that's called poly(ethylene). The long chain was made by smaller molecules from crude oil.

When these bags are burnt for disposal, they release toxic fumes. One being carbon monoxide.

Given that coal used by electric power plants has a heating value of 27.5 million btus metric ton (25 million btus per ton), det
fredd [130]

Answer:

• 36.4 kg of coal.

• 80 pounds of coal.

Explanation:

Using proportionality constant,

Mass of coal = 1,000,000/27,500,000 btus/metric ton

= 0.0364 metric tons of coal

Mass of coal = 1,000,000/25,000,000 btus/ton

= 0.04 tons of coal.

Converting metric tons to kilogram,

1 metric ton = 1000kg,

0.0364 metric ton;

= 36.4 kg of coal.

Converting tons to pounds,

1 ton = 2000 pounds,

0.04 metric ton;

= 80 pounds of coal.

A train moves with a constant velocity for 15s for 155m. How fast is the train moving?
bonufazy [111]

Answer: 10.3m/s

Explanation:

In theory and for a constant velocity the physics expression states that:

Eq(1):  distance  = velocity times time <=> d = v*t    for v=constant.

If we solve Eq (1) for the velocity (v) we obtain:

Eq(2):  velocity  = distance divided by time <=> v = d/t

Substituting the known values for t=15s and d=155m we get:

v = 155 / 15 <=> v = 10.3
