I think there are two sources:

The solar thermal and biogas in the country regions

The solar hydrogen in Urban regions.

Hi Sandip A Kale ,

understanding a "sustainable future" as a future with economic development that is conducted without depletion of natural resources, and knowing that our sun would last about five billion (5,000,000,000) years more, then the solar energy would be a good candidate for energy source in general, not just for cooking!

Hope this helps!

If an energy isn't readily available and cheap to install and maintain, then that Energy isn't sustainable. In as much as solar energy is free, let's ask ourselves, how many people can afford it in underdeveloped and developing nation's?

I see a better future with biofuel and biogas because it's installation is quite cheaper

I respectfully disagree with Iwuozor Ogemdi Kingsley , according to the Energy and Sustainability Network, the Developing countries are "in a unique position to bypass the carbon intensive power systems that other parts of the world are now trying to replace". Many developing countries have abundant solar resources and their use of fossil fuel is expensive, Such countries could achieve wide-scale deployment of solar energy in their electricity systems, especially as the price of solar energy continues to rapidly fall. By creating more ambitious goals for solar, developing countries can create a greener, cheaper path to continued development. " Unlike the developed world where solar must compete with low-cost technologies such as coal and gas, many developing countries get a significant portion of their generation from expensive fuel oil plants that can cost upwards of USD 0.40 per kWh. By comparison, recent estimates of the cost of solar PV in Kenya range from USD 0.17-0.3 per kWh and the most recent renewable energy auctions in South Africa achieved bid prices of USD 0.10 per kWh. Based on data for 100 out of 156 developing countries, 20% of the total electricity generated comes from fuel oil plants, rising to 45% if only least developed countries are considered. Therefore, solar represents a significant economic opportunity to reduce the use of fuel oil and the cost of generation."

I think there are two sources:

The solar thermal and biogas in the country regions

The solar hydrogen in Urban regions.

Natural gas

The solar thermal and biomass.

Renewable or clean energy such as wind, solar, water, waves energy is an inexhaustible potential and a good example of sustainable energy and is the most accepted in developing societies.

I think solar energy

@ Martin E. Baltazar-Lopez, I appreciate your line of thought but the price and cost implication varies from country to country and can't remain the same. The price of solar installation is dependent on a lot other factors such as government policies, government preferences, e.t.c.......One of the greatest drives of a developing country is the success of it's small and medium business......can they afford the installation and maintenance of the solar equipment? I wish also add that the SDGs aren't complete if the power isn't cheap even though it is readily available. Bio-energy is currently on the rise in countries like Cameroon but still has a long way to go in Nigeria.

Problem is we are considering on initial cost yes initial cost is high but it is cheaper than the ather source of energy. SPV system life is arround 20 years if we install 1.5 kw spv system its cost arround ₹50000 i. e ₹208 per month cooking cost every month we can save ₹500. So you can analys how much money can be save in 20 year. Second thing it also reduce the pollutants that release by combustion of conventional fuel. Gov. also provides 30%subsidiary on spv system installation. So ultimately if we are thinking about our coming generation we will have to adapt the source of energy that's nature provided us on zero effect on environment.

Yes I agree with Ranjeet Kumar Jha.

We are measuring the energy in the form of Money. This is the big hurdle in utilization of renewable energy sources for various applications including cooking.

A solar photovoltaic induction cooker is available in market we can use it. Myself develop a solar air purifier and solar refrigerator, solar ro. so we will have to adapt solar energy by developing such types of systems and solar energy is a one of best sustainable energy available free of cost

Thinking on a global scale, the sustainability of natural resource use and the impact this can have on climate change, one should opt for options that use renewable resources such as solar, thermal energy. I believe that the use of biomass would also be interesting however, as there are other environmental issues that involve for example deforestation, this option would take a back seat.

Bests.

I agree with Abdelhalim Zekry , Isam Issa Omran, İbrahim Halil Yılmaz, Ranjeet Kumar Jha , and José Henrique Pastorelli Junior

As I mentioned, solar energy can be used not only for cooking which represents only a small portion of green house gases problem and thinking on the impact to climate change, the attention should be focused on avoiding burning of fossil fuels for power and heat, and transportation.

Valuable contributions by respected RG members

Answers by Dr. Martin E. Baltazar-Lopez , Dr. Naushad Khan are really good thoughts about which I am also thinking about.

Use of renewable energy to produce electricity for cooking will reduce the dependency on Fossil fuel. Reducing use of fossil fuel will beneficial in many aspects such as pollution, transportation, economy, etc.

Researchers please share your views about, using electrical energy produced from renewable energy. What are its advantages and limitations.

I will use the stored energies without seeing the sources. These energies must be characterized by a low pollution impact.

Dear Dr. Adel Oueslati very interesting and meaningful answer.

Naushad Khan

Adel Oueslati Sir can you please explore your statement.

Elsaid Elashry Sir can you please suggest any more things based on your research in the area of biomass and also any system models.

Naushad Khan

Wind and solar energy are best because they cause no problems for the environment

Hi,

My personal preference would be to use solar energy for cooking process. Though it is not completely dependable, it may save the other non-renewable energies such as fossil fuels and LPG.

Navnit Kumar Ramamoorthy Agree

I prefer solar energy for cooking.

I agree with Shakir Tuleab and with Sameer Algburi .

Microwave and solar cooking .

Solar energy is abundant, clean and non-polluting. One just has to make solar devices more efficient to make them viable. Heat from composting piles of leaves and vegetable matter could be harnessed also. Such heat could be utilized in par-cooking some dishes such as ham which ha been demonstrated. See for example https://www.bonappetit.com/test-kitchen/cooking-tips/article/how-high-end-restaurants-are-cooking-with-compost
