Advantages and Disadvantages of Wave Energy

We are all trying to be more conscious of our choices and looking towards alternative energy or renewable energy sources. Renewable energy like solar, wind, tidal, geothermal, etc. are commonly used. But when we think of ocean waves as a source of energy, there is not much we know about. So here is a look at the potential of wave energy as well as the challenges it may face. WHAT IS WAVE ENERGY? Wave energy or ocean energy or sea wave energy is the process of capturing energy from ocean or sea waves. In other words, it is power harnessed from waves. And this can be utilized for a number of different things. For example, generation of electricity, desalination of water, pumping water into reservoirs, etc. It is an untapped form of renewable energy that shows a lot of potential. Though it ...

Advantages and Disadvantages of Biomass

The world is reeling due to the unprecedented effects of climate change. We are currently facing a global climate emergency. There are relentless efforts ongoing for the process of moving into a low-carbon and sustainable future. One of the ways to call for action is to invest in cleaner energy like biomass energy. But is it as efficient and clean as it claims? WHAT IS BIOMASS? Biomass is an organic plant or animal material used for the production of energy. It uses stored energy from the sun. The process of photosynthesis absorbs the energy derived from the sun. When biomass is burned, the energy is then released as heat. It can be directly burned or converted into fuel like biogas or biofuel. Plants, woods, manure, and any waste are examples of biomass material. They are also useful in...

Advantages and Disadvantages Of Geothermal Energy

In dictionary terms, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. However, in practical terms, it a life-sustaining resource without which humans cannot survive. There are various types of energy, depending on their source and their nature. One type of energy is renewable energy. A renewable form of energy is geothermal energy. Like all other forms of energy, it has its own advantages and disadvantages. WHAT IS RENEWABLE ENERGY? As the name suggests, renewable energies are forms of energy that can be renewed. This means that their supply is unlimited. It can also mean that its supply replenishes at a rate faster than that of its consumption. The most common examples include wind, solar, geothermal, biomass,...

Advantages and Disadvantages of Hydro Energy

Among all the types of renewable energy, hydro energy is one of the most prominent ones. Governments all across the world have set up mechanisms to harness hydro energy. India also has a huge number of dams, nearly 2000 dams across the country. Like all other forms of energy, there are various advantages and disadvantages of hydro energy. WHAT IS HYDRO ENERGY? Hydropower is the energy obtained from water. Running water through turbines convert the kinetic energy of water into mechanical energy. This is done by constructing dams on already existing water bodies. These dams create a reservoir of the water present in the water body. Water falls from a height which creates force to turn the turbines. Furthermore, tidal energy is another form of hydropower. Tidal power is the r...

Advantages and Disadvantages of Wind Energy

“Desperate times require desperate measures.” This is a quotation that most of the world is familiar with. In the current context, there are various situations all around the world that can be termed as desperate times. However, one problem that poses an equal threat for people all around the world and requires immediate action from a large number of people is climate change. Conventional fuels have been a contributing factor to the current climate crisis. Hence, there is a need to replace them. There are multiple options, like wind energy, solar energy, hydro energy, etc. HOW IS WIND ENERGY GENERATED? Wind power is generated on wind farms. These wind farms make the use of wind turbines that are turned by fast winds. The kinetic energy in the wind is converted into mechanic...

Advantages and Disadvantages of Solar Energy

Slowly and steadily, technology is providing the world with newer ways to produce energy that don’t contribute to our planet’s (on the current rate, imminent) death. Various alternatives exist for non-renewable sources of energy like fossil fuels, thermal energy, etc. Wind energy, hydro energy, geothermal energy are few of the many, many options that now exist. One of them is solar energy, which has many advantages and disadvantages. WHAT IS SOLAR ENERGY? Solar heaters, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis harnessed the energy of the sun to create electricity. Techniques that help in harnessing this energy are broadly categorized into two parts: active and passive. Active solar techniques such as pho...
