Question about energy

I'm having trouble understanding the concept of energy, I do understand that almost all the energy we use on earth comes from the sun. I am no scientist, so this question may or may not make sense lol. For one thing, I was taught that 30% of the energy that is brought to the earth through sun rays is reflected back towards the sun, and 70% remains. Because energy is never created or destroyed, That 70% must keep building up right? By now the earth must contain so much energy. If this is so, then why is there so much talk about an energy crisis? Am I correct in assuming this? Or is this just a really dumb question and does something seemingly obvious happen to all of this energy?(I'm thinking it might leave earths atmosphere and go out into space) Please explain, thanks!

theres a butt load of energy in the earth but yea it gives off heat energy too so it doesnt build up indefinitely, and energy can be converted and so there really isnt an energy crises as much as theres assholes out there who own monopolies on specific types of energies or fuels, such as oils and gas when other forms, electric, solar are much better they just want that mean green, all politics really

what do you mean the earth gives off heat energy so it doesn't build up indefinitely? Are you saying that heat energy goes out into space? Do you kind of get what I'm saying? Like where does that heat energy go

hey no scientists here either lol but yeah into space and converted into different life and earth processes

The first article seems to suggest that igneous rocks hold electrical energy.
Quote:
Abstract
Electronic Charge Carriers in Igneous Rocks and their Activation through Tectonic Processes Most rocks, in particular igneous rocks of the continental crust are fairly good insulators. Whenever their electrical conductivity increases, locally or with depth along the geotherm, the increase is thought to be caused by (1) pore water, (2) intergranular carbon films, or (3) incipient partial melting.
However, there is mounting evidence that igneous rocks contain an elusive type of electronic charge carriers, totally overlooked in the past. These charge carriers are defect electrons in the O2– sublattice, O–, also known as positive holes. Normally they lie dormant in form of spin-coupled positive hole pairs, PHP, where two O– are linked in a peroxy bond, O––O–. In this paired state they are electrically inactive and undetectable. Yet, when activated, PHPs release positive hole charge carriers, which are highly mobile and turn the rocks momentarily into pure p-type semiconductors. Hence, whenever PHPs are activated, positive holes will appear. They have the potential of affecting not only the electrical conductivity of rocks but also other properties of geophysical and geochemical interest.
My contribution to the EarthScope workshop will center on the role which the elusive PHPs and positive hole charge carriers may play in large-scale tectonic and magmatic processes in the crust.

It seems to me that there is something called electromagnetic radiation, which helps to define wavelengths of light. "Electromagnetic radiation (EM radiation or EMR) is a fundamental phenomenon of electromagnetism, behaving as waves and also as particles called photons which travel through space carrying radiant energy."
Quote:
Visible radiation (light)
Visible spectrum
Above infrared in frequency comes visible light. The Sun emits its peak power in the visible region, although integrating the entire emission power spectrum through all wavelengths shows that the Sun emits slightly more infrared than visible light.[18] By definition, visible light is the part of the EM spectrum to which the human eye is the most sensitive. Visible light (and near-infrared light) is typically absorbed and emitted by electrons in molecules and atoms that move from one energy level to another. This action allows the chemical mechanisms that underly human vision and plant photosynthesis. The light which excites the human visual system is a very small portion of the electromagnetic spectrum. A rainbow shows the optical (visible) part of the electromagnetic spectrum; infrared (if it could be seen) would be located just beyond the red side of the rainbow with ultraviolet appearing just beyond the violet end.
Electromagnetic radiation with a wavelength between 380 nm and 760 nm (400–790 terahertz) is detected by the human eye and perceived as visible light. Other wavelengths, especially near infrared (longer than 760 nm) and ultraviolet (shorter than 380 nm) are also sometimes referred to as light, especially when the visibility to humans is not relevant. White light is a combination of lights of different wavelengths in the visible spectrum. Passing white light through a prism splits it up into the several colors of light observed in the visible spectrum between 400 nm and 780 nm.
If radiation having a frequency in the visible region of the EM spectrum reflects off an object, say, a bowl of fruit, and then strikes the eyes, this results in visual perception of the scene. The brain's visual system processes the multitude of reflected frequencies into different shades and hues, and through this insufficiently-understood psychophysical phenomenon, most people perceive a bowl of fruit.
At most wavelengths, however, the information carried by electromagnetic radiation is not directly detected by human senses. Natural sources produce EM radiation across the spectrum, and technology can also manipulate a broad range of wavelengths. Optical fiber transmits light that, although not necessarily in the visible part of the spectrum (it is usually infrared), can carry information. The modulation is similar to that used with radio waves.

A lot of solar radiation is converted to kinetic energy in the form of weather. The sun is the source of energy for almost all weather on earth. A lot of solar energy is also converted to energy in plants through photosynthesis. Through that route it eventually becomes the calories that keep you going. Most of the incident solar radiation is absorbed by the ocean causing water to evaporate etc.
