sSolution to cClimate cChange

Capitalisation

In this modern world, climate change is one of the biggest problems.

When you write "one of the", you should use the plural

To ensure the eEarth is a habitalble place for a long time, we need to tackle withe climate change problem.

"Earth" needs to be capitalised
We're talking about a singular planet, so we need to put "a ... place" instead of just "place"
"habital" is not a word, the closest is "habitable"
The usage of "with" says that we need to tackle with climate change, instead of "the" problem itself.

My idea for climate change is to promote electric vehicles and to construct nuclear power plants.

"is promote" should be "is to promote"
"vehicle" should be plural, so "vehicles"
Arguably a stylistic choice, "and to construct..." is somewhat easier to read.

To reduce the amount of greenhouse gases, changing theour way of transportation should be taken into consideration.

"the way of transportation" reads awkwardly, "changing our way of transportation.." is more natural
"should taken" is incorrect, it should be "should be taken"

In fact, electic cars does not produce musch greenhouse gases like methane, carbon dioxide, etc.

"electric car does..." is wrong, it can either be "the electric car does..." or "electric cars do not.."
"mush" mispelt, changed to "much"
"methan" mispelt, changed to "methane"
"carbondioxide" mispelt, changed to "carbon dioxide"

It is obvious that we need electricity to be able to use electric vehicles.

Since you're talking about electric vehicles generally, we're talking about multiple, so it should be "electric vehicles" instead of "electric vehicle".

Nuclear power plants will enable us to produce electricity in a clean way like windmills.

We're talking about nuclear power plants generally, so it should be plural: "Nuclear power plants will.."
"way like windmill" is incorrect, either "in a clean way like windmills" or "in a clean way, like the windmill".

sA Solution to climate change

In this modern world, climate change is one of the biggest problems.

To ensure the earth is a habitalble place for a long time, we need to tackle with climate change problem.

Or you could say "we need to tackle the problem/issue of climate change"

My idea forto tackle climate change is to promote electric vehicles and construct nuclear power plants.

To reduce the amount of greenhouse gases we emit, changing the way of transportation we use should be taken into consideration.

In fact, electric cars does not produce mush greenhouse gases like methane, carbon dioxide, etc.

It is obvious that we need electricity to be able to use electric vehicles.

Nuclear power plants will enable us to produce electricity in a clean way like windmillturbines.

The solution to climate change.

To ensure the earth is a habitalble place for a long time, we need to tackle withe problem of climate change problem.

My idea for climate change is to promote electric vehicles and construct nuclear power plants.

To reduce the amount of greenhouse gases, changing the waydifferent modes of transportation should be taken into consideration.

In fact, an electric car does not produce mushany greenhouse gases like methane, carbon dioxide, etc.

It is obvious that we need electricity to be able to use an electric vehicle.
