A lot of energy is inside Earth.

but utilizing it is probably completely unreal, uneconomical. But if weren't, it would suffice practically forever. Actually energy accumulated inside the Earth has the same origin as energy of the Sun, from the beginning of everything. This is like a small Sun inside the Earth.
Purely renewable energy source doesn't exist.
Even the Sun shining from 4.6 billion years will go out, in 5 billions years, perhaps the Earth sooner or later will fall on it in my opinion because is SLOWING DOWN.

Thermal energy from within the Earth is practicable only if it is close enough to the surface and if that local source is stable and has the capacity to supply adjacent communities, which is why Iceland has been able to use it. Once the source is deeper, costs rise exponentially, particularly to cope with corrosive liquid mixes at high temperatures, which is when they are most reactive.

The Earth is, of course, slowing down, which is why we need to adjust time-based measurements and certain industries and devices, to cope with a leap-second** every so often

**A leap-second is a one-second adjustment that is occasionally applied to Coordinated Universal Time (UTC) in order to keep its time of day close to the mean solar time, or UT1. (Thanks Wikipedia!)

In dinosaurs' times for example the length of the day length was close to about 23 hours:

It was not so long ago. And perhaps the Moon will fall on the Earth like in Time machine. But maybe next planets, frozen today, will be warmer, because most likely they slow down too ? It depends on energy loosing rate by the Sun, maybe they won't be late.

Sounds like one of those scare articles you read in the Daily Mail or Daily Express.
They often have headlines like,'Giant Meteor Heading towards Earth' or 'Turkey Downs Russian Jet:Is This The Start Of World War 3?'
I'm off to the pub to cheer myself up.
Cheers!

Nope, the Moon is getting more distant, due to tidal friction :t:

Indeed. It's receding from Earth at about 3.5cm per year, sufficient to require fresh calculations for spacecraft sent to the other side of the Moon or to orbit it, or to land on it.

A bit off thread! But did anyone else see Cameron talking at the climate summit talking tough on climate change? Yet just 6 days previously Osborne was anouncing this!!!

...and yet the UK Government regularly seems genuinely baffled that ordinary people employ joined-up thinking as routine in their lives. This is merely the latest in an embarrassingly long line of decisions and political scenarios that would be deemed too far-fetched if presented in a novel. Truly fulfilling the proverb for futile action, immortalised in:

"...He marched them up to the top of the hill,
And he marched them down again.

And when they were up, they were up,
And when they were down, they were down,
And when they were only half-way up,
They were neither up nor down."
