Yes indeed it can be. Any source of energy is potentially dangerous to some degree or another, but it can depend upon how extreme or absurd a situation you might want to imagine. Ultra-violet light from sunlight is totally natural but could cause sunburn or even skin cancer, which is neither extreme nor absurd, but equally a gentle breeze is totally natural and it could dislodge a small twig from a tree and it might just stab you in the eye. That might sound absurd and very improbable but it does at least illustrate how any form of energy can be dangerous.
natural energy sources
they are both natural sources of energy
one natural resource is the sun
Natural sources refer to resources that occur in nature and are not manufactured. Examples include sunlight for solar energy, wind for wind power, rivers for hydropower, and wood for biomass energy. Other natural sources include geothermal energy from the Earth's heat and tidal energy from the oceans.
nonrenewable energy sources are sources that are depleted sources as fossil fuels (wood, coal, natural gas, and oil)
Natural energy sources
They are all energy sources.

Natural resources
Conventional energy sources are coal, oil, natural gas, and hydraulic energy sources.Non conventional energy sources are nuclear, solar, wind, geothermal, wave, tide, and biomass energy sources.
Coal, oil, and natural gas are the main three nonrenewable primary energy sources.
