Rechargeable cells are in use, the aim is to improve them to store more energy.
Examples of usable items include a smartphone, a desktop computer, and a bicycle. Examples of unusable items could be a broken lightbulb, a deflated basketball, or a rusted screwdriver.

Earth's main types of resources can be depleted through overexploitation, pollution, and habitat destruction. Overuse of resources like water, fossil fuels, and minerals can lead to their depletion. Pollution can make resources unusable, while habitat destruction can disrupt ecosystems and reduce available resources.
Soil can become depleted of nutrients and lose its ability to support plant growth over time, but it doesn't technically "expire." With proper care and amendments, soil can be revitalized for gardening.
Patriots experienced problems such as their weapons becoming soaked and unusable, icy roads prevented walking, & 900 men captured.
Cheap electric ovens may run out of power and become unusable in power outage situations. They may also have poor quality and cannot properly cook foods.

To prevent caulking tube caps from drying out and becoming unusable, store them upside down in a jar filled with water. This will create a seal and keep the cap moist, allowing it to be reused multiple times. Additionally, make sure to clean the cap after each use to remove any dried caulk that could prevent a proper seal.
Groundwater can become depleted through over-extraction for agricultural, industrial, or municipal purposes, leading to lower water tables and dried-up wells. Pollution can also render groundwater unusable for certain purposes, contributing to depletion as it becomes unfit for consumption. Additionally, climate change impacts like reduced precipitation can affect recharge rates, further depleting groundwater resources.
Perpetual motion machines are theoretical machines that aim to create unlimited energy without an external source but violate the laws of thermodynamics, making them impossible to create in reality. Other examples of machines that create unusable energy could include inefficient or poorly designed machines that waste energy in the form of heat, noise, or other non-usable forms.

Some cautions of using a cheap electric blanket are the blanket could short out and cause a fire, the thermostat that controls the temperature may not work accurately and cause burns or dehydration. The material may also fall apart and be unusable.
